-Users can now specify animation params on a per flame basis.
--These get saved with the flame file.
-Allow for rotating xforms around the world origin during animation.
-Make the Clear Flame menu item be more comprehensive in how it clears a flame out.
--Bug fixes
-Fix an extremely rare possible memory leak when using motion during animation, which is never used in Fractorium.
-Do not skip to the current flame index, or attach a prefix in the Final Render Dialog when rendering an animation sequence.
--Code changes
-Place all animation params in Ember.
-Add new preset dimensions to the right click menu of the width and height fields in the editor.
-Change QSS stylesheets to properly handle tabs.
-Make tabs rectangular by default. For some reason, they had always been triangular.
--Bug fixes
-Incremental rendering times in the editor were wrong.
--Code changes
-Migrate to Qt6. There is probably more work to be done here.
-Migrate to VS2022.
-Migrate to Wix 4 installer.
-Change installer to install to program files for all users.
-Fix many VS2022 code analysis warnings.
-No longer use byte typedef, because std::byte is now a type. Revert all back to unsigned char.
-Upgrade OpenCL headers to version 3.0 and keep locally now rather than trying to look for system files.
-No longer link to Nvidia or AMD specific OpenCL libraries. Use the generic installer located at OCL_ROOT too.
-Add the ability to change OpenCL grid dimensions. This was attempted for investigating possible performance improvments, but made no difference.
This has not been verified on Linux or Mac yet.
--User changes
-Allow users to set the Exp value when using the Exp temporal filter type.
-Set the default temporal filter type to be Box, which does not alter the palette values at all during animation. This is done to avoid confusion when using Gaussian or Exp which can produce darkened images.
--Bug fixes
-Sending a sequence to the final render dialog when the keyframes had non zero rotate and center Y values would produce off center animations when rendered.
-Temporal filters were being unnecessarily recreated many times when rendering or generating sequences.
-Exp filter was always treated like a Box filter.
--Code changes
-Add a new member function SaveCurrentAsXml(QString filename = "") to the controllers which is only used for testing.
-Modernize some C++ code.
-Add backward compatibility option for the following variations: cos, cosh, cot, coth, csc, csch, sec, sech, sin, sinh, tan, tanh.
-Add the ability to re-order variations by dragging them in the Info tab.
-Improve performance in the following variations: cpow2, dc_cube, julia3d, julia3dz, julian2, log_db, nblur, npolar, waffle, wavesn, xtrb.
--Code changes
-Rand range now uses multiply + shift rather than modulo.
-Support 4k monitors, and in general, properly scale any monitor that is not HD.
-Allow for a spatial filter of radius zero, which means do not use a spatial filter.
-Add new variations: concentric, cpow3, helicoid, helix, rand_cubes, sphereblur.
-Use a new method for computing elliptic which is more precise. Developed by Discord user Claude.
-Remove the 8 variation per xform limitation on the GPU.
-Allow for loading the last flame file on startup, rather than randoms.
-Use two different default quality values in the interactive renderer, one each for CPU and GPU.
-Creating linked xforms was using non-standard behavior. Make it match Apo and also support creating multiple linked xforms at once.
--Bug fixes
-No variations in an xform used to have the same behavior as a single linear variation with weight 1. While sensible, this breaks backward compatibility. No variations now sets the output point to zeroes.
-Prevent crashing the program when adjusting a value on the main window while a final render is in progress.
-The xaos table was inverted.
--Code changes
-Convert projects to Visual Studio 2017.
-Change bad vals from +- 1e10 to +-1e20.
-Reintroduce the symmetry tag in xforms for legacy support in programs that do not use color_speed.
-Compiler will not let us use default values in templated member functions anymore.
--Add support for Exr files which use 32-bit floats for each RGBA channel. Seems to come out too washed out.
--Allow for clearing an individual color curve.
--Allow for saving multiple image types in EmberRender and EmberAnimate. All writes are threaded.
--Remove --bpc command line argument. Add format png16 as a replacement.
--Remove --enable_jpg_comments and --enable_png_comments command line arguments, and replace them with --enable_comments which applies to jpg, png and exr.
--Add menu items to variations and affine spinners which allow for easy entry of specific numeric values like pi.
--Make final render dialog be wider rather than so tall.
Bug fixes:
--Fix some OpenCL compile errors on Mac.
--Remove ability to save bitmap files on all platforms but Windows.
Code changes:
--New dependency on OpenEXR.
--Allow Curves class to interact with objects of a different template type.
--Make m_Curves member of Ember always use float as template type.
--Set the length of the curves array to always be 2^17 which should offer enough precision with new 32-bit float pixel types.
--Set pixel types to always be 32-bit float. This results in a major reduction of code in the final accumulation part of Renderer.h/cpp.
--Remove corresponding code from RendererCL and FinalAccumOpenCLKernelCreator.
--Remove Transparency, NumChannels and BytesPerPixel setters from Renderer.h/cpp.
--Add new global functions to format final image buffers and place all alpha calculation and scaling code in them.
--Blending is no longer needed in OpenGLWidget because of the new pixel type.
--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.
--Remove some unused functions.
--User changes
-Make all fonts be MS Shell Dlg 2. This will require reloading dark.qss if users are already using it.
-Limit size of the left side of the palette editor.
-Disable create from image buttons in the palette editor when working on a fixed palette.
--Bug fixes
-The following variations were wrong: coshq, cothq.
-During iteration, the color index could become nan if all xform color speeds were negative. This could lead to bad results on the GPU. Fix to check for nan. Minimal speed difference.
--Code changes
-Make the following variations safer by using Zeps(): sinq, sinhq, secq, sechq, tanq, tanhq, cosq, coshq, cotq, cothq, cscq, cschq, estiq.
-Always pass -cl-no-signed-zeros -cl-denorms-are-zero to kernel compiles for both single and double.
-Flush all denormals to zero for all executable programs. This will likely lead to a speedup for badly behaving programs.
--User changes
-Add many tooltips to help clarify functionality.
-Select multiple flames in library for del/move. Still only one allowed to be set as the current.
-Show checkbox for current flame. Remember this is not necessarily what's selected.
-User can now drag a square to select xforms, which keeps in sync with checkboxes.
-Remove --nframes from command line. Replace with new params: --loopframes, --interpframes, --interploops.
-Add two new options to EmberGenome: --cwloops --cwinterploops to specify whether rotation should go clockwise instead of the default counter clockwise.
-Add these to Fractorium as checkboxes.
-Apply All now also works for toggling animate flag on xforms.
-Options dialog now allows user to set whether double click toggles spinners, or right click does.
--Bug fixes
-Selecting final and non-final xforms, and then dragging the non-final did not drag the final with it.
-Selecting all xforms when a final was present, then deleting crashed the program.
-Remove support for ppm files in the command line programs, it's an outdated format.
-Switching between SP and DP kept reapplying the palette adjustments.
--Code changes
-Move build system to Visual Studio 2015 and Qt 5.6.
-SSE used during addition of points to the histogram.
-Remove last remnants of old flam3 C code and replace with C++.
-Remove unused code involving tbb::task_group.
-Make settings object a global shared_ptr singleton, so it doesn't have to be passed around.
-Add animation sequence creation to Fractorium.
-Add two new options to EmberGenome which are used when generating an animation sequence.:
--startcount: Add this number to the filename of each flame.

--Bug fixes
-Prevent filenames in command line programs from using scientific notation when rendering a large number of frames.
-Fix tab orders to match newer GUI items which were overlooked in previous releases.
-Re-render previews if transparency value in the options dialog was changed. Re-rendering was previously only done if early clip or y axis up was changed.
-Use transparency when rendering thumbnail previews.
--Code changes
-Wrap EmberCommon.h in a namespace called EmberCommon.
-Move FormatName() from EmberGenome to EmberCommon.h/cpp
-Add a prefix parameter to EmberFile::DefaultFilename() to allow for creating a default filename for sequences.
-When showing the final render dialog, allow specifying where it came from: the toolbar or the render sequence button.
-Refactor all preview rendering code out into its own class hierarchy with overrides for the main window and the final render dialog.
-Remove all preview render cancelling functions, they are now built into the new class hierarchy and a new render will not start until the previous one is stopped.
-Add two new function ConstrainLow() and ConstrainHigh() which wrap constraining two min/max spinboxes to each others' values.
-Add a bool to FractoriumEmberControllerBase::CopyEmberFile() to specify whether to copy the main file or the sequence file. This is somewhat of a hack and was done in a rush.
-Add a bool to FractoriumEmberControllerBase::SetEmberFile() to specify whether to move the file rather than copy. This is used in FinalRenderEmberController and improves efficiency.
-Add wrapper functions for variations filter dialog settings.
-Add a new option --statevars to EmberGenome to list the variations which change state.
-Allow for filtering in the Variations Dialog based on the same types listed in the EmberGenome options.
--Code changes
-More correctly populate VariationList::m_ParametricVariations and VariationList::m_NonParametricVariations to account for variations which have params only used for precalc.
-Consolidate some of the code in VariationList which searches by name.
-Add new options to EmberGenome to better help assess which variations have certain characteristics. The options are:
--sumvars: Display the names of all regular variations which have the default behavior of summing their outputs and exit.
--assignvars: Display the names of all regular variations which have the non-standard behavior of assigning their outputs and exit.
--ppsumvars: Display the names of all pre/post variations which have the non-standard behavior of summing their outputs and exit.
--ppassignvars: Display the names of all pre/post variations which have the default behavior of assigning their outputs and exit.
--dcvars: Display the names of all variations which use direct coloring and exit.
--parvars: Display the names of all variations which have parameters and exit.
--nonparvars: Display the names of all variations which do not have parameters (weight only) and exit.
--Code changes
-Make VariationList vectors have const elements since no callers should ever change them.
-Add new function to VariationList to retrieve a const ref to the parametric variations.
-Move some search functions out of EmberTester and into EmberCommon.h.
-General code cleanup.
-Highlight power is now on by default.
-Allow for adjustments on the Flame tab to apply to all open flames in the file.
-Add two new buttons to the color tab to randomize and toggle the xform color indices.
-Remove the --strip option from EmberGenome. It was useless and was likely just a carry over from flam3 during its early debugging stages when testing strips.
-Make randoms in EmberGenome have default dimensions of 1920 x 1080.
-Prevent --inter and --rotate in EmberGenome from rotating backward before the first flame since it doesn't really make sense.
-Ensure every loaded flame has at least one xform in it.
-Change dark.qss to hide dotted selection outline around checkboxes. Users must reload it to take effect.
--Bug fixes
-The saving of last.flame during editing was appending the file when it should have been replacing.
-It was impossible for EmberGenome to create a random flame. It can now be done by specifying no arguments: EmberGenome.exe
-Crossing in EmberGenome was not logging the performed actions to the edit Xml tag.
-Apply sub batch size and fuse count to template files used on the command line.
-Use new default filter types with template files.
--Code changes
-Use cerr in SheepTools instead of cout.
-Set m_SubBatchSize and m_FuseCount to default values in Ember::Clear().
-Clean up some command line options text formatting.
-Always force times of each flame to increase from zero when saving a file.
-Remove check for times when doing a sequence in EmberGenome because the original times are never used there.
--Bug fixes
-Multi-GPU synchronization was not actually thread safe and was likely doing less iters than requested. It is now properly synchronized.
--Code changes
-Optimize Interpolater by making it a non-static class by adding some members used for caching values during interpolation.
-Cache values in SheepTools as well, which was already a non-static class.
-General cleanup.
--Bug fixes:
-Fix crash when using smooth interpolation in EmberGenome.
-Print error and exit EmberGenome when sequencing if times are not
sorted.
--Code changes:
-Another attempt at Singleton. This reverts the design to what it was
before with a fix to the code that was causing it not to behave like a
singleton should.
-crackle is now 5-10 times faster as a result of using cached values as is done on the CPU. These were previously omitted due to a bug elsewhere in the code that was erroneously attributed to the crackle caching mechanism.
-Report precision in command line programs.
-Edits will not save back to the file in memory on render completion when preview renderer is running.
--Bug fixes
-dc_perlin was crashing on Nvidia when using SP.
-Duplicate images were randomly getting added to the file in memory.
-Crash when opening an Xml with less than 2 flames in it.
--Code changes
-Use raw array of floats in OpenCL for perlin noise, rather than float3/double3.
-Add some default cases to dc_perlin.
-Redo singleton pattern yet again. Deriving from a templated Singleton<T> class was creating a separate instance per module. Now only one instance of each type will ever be created and it will be wrapped in a shared_ptr which guarantees its deletion as main() exits.
-The concept of "saving back to file in memory" has been removed. The current ember is saved back to memory whenever the render completes and the thumbnail will be updated each time.
-Command line programs now default to using double precision.
-The --bits argument has been removed and replaced with --sp to specify single precision. If omitted, DP is used.
-Remove the --seed option, it was never used.
-Remove the --sub_batch_size option, it has been part of the Xml for a long time.
-Remove --hex_palette argument for EmberRender, it only makes sense in EmberAnimate and EmberGenome.
-Set enable_jpg_comments and enable_png_comments to false by default. It was a very bad idea to have them be true because it reveals the flame parameters used to render the image which many artists guard closely.
--Bug fixes
-Continuous update was broken.
-Undo list was broken with new Library tab design.
-Force repaint on xform checkbox change to ensure circles are immediately drawn around selected xforms.
--Code changes
-Remove save to back to file in memory icon, document-hf-insert.png.
-Remove the option --intpalette to format the palette in the xml as ints. If they are not hex formatted, then they should always be float. This option was pointless.
-Cleanup some options text for the command line programs.
-Allow for dragging around flames in the library tab. This is useful for setting up the order of an animation.
-Make the opening of large files in Fractorium much more efficient when not-appending.
-Make the opening of large files in all EmberRender and EmberAnimate more efficient.
-Better error reporting when opening files.
--Bug fixes
-Get rid of leftover artifacts that would appear on preview thumbnails when either switching SP/DP or re-rendering previews.
-Filename extension was not being appended on Linux when saving as Xml, thus making it impossible to drag that file back in becase drop is filtered on extension.
--Code changes
-Move GCC compiler spec to C++14. Building with 5.3 now on linux.
-Use inline member data initializers.
-Make a #define for static for use in Utils.h to make things a little cleaner.
-Make various functions able to take arbitrary collections as their parameters rather than just vectors.
-Make library collection a list rather than vector. This alleviates the need to re-sync pointers whenever the collection changes.
-Subclass QTreeWidget for the library tree. Two new files added for this.
-Remove all usage of #ifdef ROW_ONLY_DE in DEOpenCLKernelCreator, it was never used.
-Add move constructor and assignment operator to EmberFile.
-Add the ability to use a pointer to outside memory in the renderer for the vector of Ember<T>.
-Make a lot more functions const where they should be.
-Really fix locking of affine scale.
--Code changes
-Remove dependency projects from the solution. Move to a project design where they are built once via command line and stored in a /Deps folder.
--Because of this, libpng is built as a static lib instead of a dll because that's what its command line makefile supports.
--Remove libpng16.dll from Wix installer.
-Remove all configs except for debug and release.
-Remove all platforms except for x64.
-Add #define __TBB_NO_IMPLICIT_LINKAGE 1 to prevent tbb from locking for tbb_debug.lib by default on debug builds.
-Put Ember.rc in a filter folder in the project.
-Place pragma warning disable statements in PCH files rather than in projects. This makes it easier when using Qt Creator.
-Move all resource files to the MSVC folder.
-Set all targets in QtCreator project to their lowercase names to be more *nix friendly. Set -l link statements to use these new lowercase names for ember and embercl.
-Rework projects to favor shadow builds.
-Remove the symlinks.sh file and all references to it. It was never needed. Instead, just specify multiple include and link paths in the .pro files.
-Change WIN32 to _WIN32.
-Fix a few code warnings.
-Split VariationList into .h/cpp files.
--Make VariationList.cpp the only place where the variations files are included from. This speeds up the build, but variations can no longer be directly instantiated.
--Variations are no longer exported.
-Add 4 new possible arguments to EmberGenome:
--allvars: Print the names of all supported variations.
--regvars: Print the names of all supported regular variations.
--prevars: Print the names of all supported pre variations.
--postvars: Print the names of all supported post variations.
-Add variations changes to the list of functionality that can be applied to all xforms using the Select tab.
-Allow for graphical affine adjustments to apply to multiple selected xforms.
-Slight optimization of the pie variation.
-Undo state is only saved when the render completes and the mouse buttons are released. This helps avoid intermediate steps for quickly completing renders while dragging.
-Add some keyboard shortcuts for toolbar and menu items.
-Make info tab tree always expanded.
--Bug fixes
-Make precalcs for all hypertile variations safer by using Zeps() for denominators.
-Changing the current xform with more than one selected would set all xform's color index value that of the current one.
-Use hard found palette path information for randoms as well.
-OpenCL build and assignment errors for Z value in epispiral variation.
-Unitialized local variables in hexaplay3D, crob, pRose3D.
--Code changes
-Change static member variables from m_ to s_.
-Get rid of excessive endl and replace with "\n".
-Remove old IMAGEGL2D define from before Nvidia supported OpenCL 1.2.
-Remove old CriticalSection code and use std::recursive_mutex.
-Make Affine2D Rotate() and RotateTrans() take radians instead of angles.
-More C++11 work.
-General cleanup.
-Allow for pausing the renderer in the main window. This makes is more efficient when entering many parameters, such as when following a tutorial.
-Add support for new variations: erf, gamma, jac_cn, jac_dn, jac_sn, logDB, pressure_wave, pRose3D, splits3D, w, waves2b, x, xerf, y, z.
-Inform user of the start and stop of file parsing in EmberAnimate because the files could potentially be very large.
-Move the follwing fields to a new table called Animation: Interpolation, Affine Interpolation, Temporal Samples, Temporal Filter Width, Temporal Filter Type.
-These currently have no effect on the interactive renderer and instead are used when running flames through EmberGenome to generate sequences, and then animating them in Fractorium or EmberAnimate.
-Add new parameter overrides for EmberRender and EmberAnimate which directly assign values to all flames being rendered, rather than scale:
--quality
--demin
--demax
--Bug fixes
-Left pad instead of right pad names of sequence outputs from EmberGenome.
-Unique file naming was broken for files which already had an underscore in them.
-Properly report that png is the default format of EmberRender and EmberAnimate output instead of erroneously claiming it was jpg.
-Make command line programs search these folders in this order for the palette file:
./
~/.fractorium
~/.config/fractorium
/usr/share/fractorium
/usr/local/share/fractorium
-Fix possible bad values in hexes.
-Better assignment of Z variables.
-Fix boarders due to use of poorly implemented rint() function from flam3. Use std::rint() now.
-wedge_sph was completely wrong due to having accidentally swapped the mapping of two parameters.
-Make juliascope juliascope_power parameter be of type REAL_NONZERO since it's used as a denominator.
-Make Z assignment compatible with the originals in:
-arch, bcircle, bCollide, bent, bent2, bisplit, blob, blur_linear, blur_square, bMod, boarders, boarders2, bSwirl, bTransform, butterfly, cardioid, cell, circleblur, circlize, circlize2, circus, collideoscope, cos, cosine, cosh, coth, cpow, cpow2, crescents, cropn, csc, csch, curl, curve, dc_gridout, deltaa, diamond, disc2, eclipse, eCollide, edisc, eJulia, elliptic, eMod, eMotion, ennepers, epispiral, ePush, eRotate, eScale, eSwirl, ex, exp, expo, exponential, fan, fdisc, fibonacci, fibonacci2, fisheye, flipcircle, flipy, flower, flux, funnel, glynnia, GlynnSim1, GlynnSim2, GlynnSim3, gridout, handkerchief, heart, hole, idisc, julia, julian2, juliaNab, kaleidoscope, lazyTravis, Lissajous, mask, MobiusN, mobius_strip, modulus, murl, murl2, npolar, ortho, oscilloscope, parabola, perspective, petal, phoenix_julia, pie (was also inconsistent between cpu and gpu), poincare, popcorn, popcorn2, power, pow_block, rational3, rays, rblur, rings, rippled, roundspher, sec, secant2, sigmoid, sin, sineblur, sinh, sinusgrid, sphericaln, spiralwing, spirograph, split, squarize, squirrel, squish, sschecks, starblur, stripes, stwin, super_shape, tan, tancos, tangent, tanh, TwinTrian, twoface, unpolar, waves, wavesn, wedge_julia, whorl, xheart, zblur, zscale.
--Code changes
-Generalize Variation::PrecalcHelper() and rename to PrePostPrecalcHelper().
--Do the same for the OpenCL version and rename it PrePostPrecalcOpenCLString().
-Rename Variation::m_AssignType to m_PrePostAssignType since it's only relevant to pre/post variations.
-Convert all enums to class enum to be consistent with C++11 style.
-Convert some if/else statements in filter classes to case statements.
-Add overloaded stream operators to print various enums.
-Convert all enums to class enum to be consistent with C++11 style.

-Add new variations: crackle, dc_perlin.
-Make default palette interp mode be linear instead of step.
-Make summary tab the selected one in the Info tab.
-Allow for highlight power of up to 10. It was previously limited to 2.
--Bug fixes
-Direct color calculations were wrong.
-Flattening was not applied to final xform.
-Fix "pure virtual function call" error on shutdown.
--Code changes
-Allow for array precalc params in variations by adding a size member to the ParamWithName class.
-In IterOpenCLKernelCreator, memcpy precalc params instead of a direct assign since they can now be of variable length.
-Add new file VarFuncs to consolidate some functions that are common to multiple variations. This also contains texture data for crackle and dc_perlin.
-Place OpenCL versions of these functions in the FunctionMapper class in the EmberCL project.
-Add new Singleton class that uses CRTP, is thread safe, and deletes after the last reference goes away. This fixes the usual "delete after main()" problem with singletons that use the static local function variable pattern.
-Began saving files with AStyle autoformatter turned on. This will eventually touch all files as they are worked on.
-Add missing backslash to CUDA include and library paths for builds on Nvidia systems.
-Add missing gl.h include for Windows.
-Remove glew include paths from Fractorium, it's not used.
-Remove any Nvidia specific #defines and build targets, they are no longer needed with OpenCL 1.2.
-Fix bad paths on linux build.
-General cleanup.
-Add new variations: bubbleT3D, crob, hexaplay3D, hexcrop, hexes, hexnix3D, loonie2, loonie3, nBlur, octapol and synth.
-Allow for pre/post versions of dc_bubble, dc_cylinder and dc_linear whereas before they were omitted.
-When saving a file with multiple embers in it, detect if time values are all the same and if so, start them at zero and increment by 1 for each ember.
-Allow for numerous quality increases to be coalesced into one. It will pick up at the end of the current render.
-Show selection highlight on variations tree in response to mouse hover. This makes it easier to see for which variation or param the current mouse wheel action will apply.
-Make default temporal samples be 100, whereas before it was 1000 which was overkill.
-Require the shift key to be held with delete for deleting an ember to prevent it from triggering when the user enters delete in the edit box.
-This wasn't otherwise fixable without writing a lot more code.
--Bug fixes
-EmberGenome was crashing when generating a sequence from a source file with more than 2 embers in it.
-EmberGenome was improperly handling the first frame of a merge after the last frame of the loop.
-These bugs were due to a previous commit. Revert parts of that commit.
-Prevent a zoom value of less than 0 when reading from xml.
-Slight optimization of the crescents, and mask variations, if the compiler wasn't doing it already.
-Unique file naming was broken because it was looking for _# and the default names ended with -#.
-Disallow renaming of an ember in the library tree to an empty string.
-Severe bug that prevented some variations from being read correctly from params generated outside this program.
-Severe OpenCL randomization bug. The first x coordinates of the first points in the first kernel call of the first ember of a render since the OpenCL renderer object was created were not random and were mostly -1.
-Severe bug when populating xform selection distributions that could sometimes cause a crash due to roundoff error. Fix by using double.
-Limit the max number of variations in a random ember to MAX_CL_VARS, which is 8. This ensures they'll look the same on CPU and GPU.

-Redesign how functions are used in the variations OpenCL code.
-Add tests to EmberTester to verify some of the new functionality.
-Place more const and override qualifiers on functions where appropriate.
-Add a global rand with a lock to be used very sparingly.
-Use a map instead of a vector for bad param names in Xml parsing.
-Prefix affine interpolation mode defines with "AFFINE_" to make their purpose more clear.
-Allow for variations that change state during iteration by sending a separate copy of the ember to each rendering thread.
-Implement this same functionality with a local struct in OpenCL. It's members are the total of all variables that need to change state within an ember.
-Add Contains() function to Utils.h.
-EmberRender: print names of kernels being printed with --dump_kernel option.
-Clean up EmberTester to handle some of the recent changes.
-Fix various casts.
-Replace % 2 with & 1, even though the compiler was likely doing this already.
-Add new file Variations06.h to accommodate new variations.
-General cleanup.
-Add a new dialog for editing QSS stylesheets. Allow for saving, reloading and setting styles as default.
--Include a dark style with the installation called dark.qss.

Fix incorrect iters ran/requested percentage in EmberAnimate to match EmberRender.
Fix motion blur being disabled when doing animations in final render dialog.
Allow for boolean command line options which default to true to be set to false.
--Code Changes
Add resource files for Ember and EmberCL.
Capture work since the last release in VersionHistory.txt.
-Add support for multiple GPU devices.
--These options are present in the command line and in Fractorium.
-Change scheme of specifying devices from platform,device to just total device index.
--Single number on the command line.
--Change from combo boxes for device selection to a table of all devices in Fractorium.
-Temporal samples defaults to 100 instead of 1000 which was needless overkill.
--Bug fixes
-EmberAnimate, EmberRender, FractoriumSettings, FinalRenderDialog: Fix wrong order of arguments to Clamp() when assigning thread priority.
-VariationsDC.h: Fix NVidia OpenCL compilation error in DCTriangleVariation.
-FractoriumXformsColor.cpp: Checking for null pixmap pointer is not enough, must also check if the underlying buffer is null via call to QPixmap::isNull().
--Code changes
-Ember.h: Add case for FLAME_MOTION_NONE and default in ApplyFlameMotion().
-EmberMotion.h: Call base constructor.
-EmberPch.h: #pragma once only on Windows.
-EmberToXml.h:
--Handle different types of exceptions.
--Add default cases to ToString().

-EmberCLPch.h:
--#pragma once only on Windows.
--#include <atomic>.
-IterOpenCLKernelCreator.h: Add new kernel for summing two histograms. This is needed for multi-GPU.

-Misc: Convert almost everything to size_t for unsigned, intmax_t for signed.
-Remove Hue as a saved parameter, as well as animation parameters associated with it. It's now a GUI-only field that is never saved.
-Make histogram, density filter buffer, and all associated fields always float, even when using double. In that case, only the iteration calculations are now double. Suggested by Thomas Ludwig.
-Print all three kernels in EmberRender when the --dump_kernel option is specified.
-Apply variations filter to randoms.
--Bug fixes
-Fix bug where hue was not being preserved when switching controllers and embers. Very hard to repro bug, but mostly overcome by eliminating hue as a saved parameter.
--Code changes
-De-templatized DEOpenCLKernelCreator and FinalAccumOpenCLKernelCreator. They now just take a bool as a parameter to specify double precision.
-To accommodate the buffers being float, introduce a new #define types in EmberCL called real4_bucket, and real4reals_bucket.
-Density and spatial filtering structs now use this type.
-ConvertDensityFilter() and ConvertSpatialFilter() no longer return a value, they just assign to the member.
-Add motion support from Simon Detheridge at the ember level instead of just individual xforms:
Add the ability to manipulate camera pitch, yaw and other goodies during flame rotation using a new element specified at the top-level of the flame.
Create a new 'saw' motion function, so that these values can effectively be looped (e.g. yaw -1 to +1) over the course of a rotation.
Add an offset to existing motion elements, to start them partway through their cycle. This would (for example) enable creating circular motion of xform affines, by combining two offset sine waves, one with an offset of 0.25 or 0.75.
Fix loops in EmberGenome (they only had an on/off effect - this was broken in flame-genome as well) and make the loop count floating-point as well. For sequence animations, it's not necessary for clips to loop precisely if they're not designed specifically for the ES project.
Similarly, there's no need for motion_frequency to be an integer value either so this was changed to allow motion that doesn't necessarily start or end at the loop boundary.
I've attempted to keep each bit of functionality in its own commit.
There's an argument as to whether to call the new flame motion elements <flame_motion/> (to differentiate programmatically) or just <motion/> (for consistency within the file) -- I opted for the former because it was easier to modify the xml parser that way.
--Code changes
-Change FlameMotion.h to EmberMotion.h to keep the naming convention consistent.
-Made elements of EmberMotion.m_MotionParams into their own type, MotionParam, which allows for CopyVec() to work.
-Change m_FlameMotionElements to m_EmberMotionElements in Ember.
-Use CopyVec() for EmberMotion instead of manual copy in copy constructors.
-Add exports in Ember.cpp for EmberMotion.
-Format eEmberMotionParam enum with one entry per line since it has many entries.
-Use fabs() in XmlToEmber instead of glm::abs.
-Minor formatting.
-Allow for empty fields in template files.
--Code changes
-When parsing, a boolean is not available to specify whether to use the default values if they are not present. This will be false for template files.
Add Curves.h, and CurvesGraphicsView.h/cpp to support bezier color curves.
Add Curves member to Ember.
Add curves capability to EmberCL.
Remove some unused variables in the kernel created in RendererCL::CreateFinalAccumKernelString().
Use glm namespace for vec classes if GLM_VERSION >= 96, else use glm::detail.
As a result of using glm namespace, all instances of min and max had to be qualified with std::
Split ComputeCamera into that and ComputeQuality().
Reduce the amount of ComputeCamera() and MakeDmap() calls on each incremental iter that doesn't use temporal samples.
Fix clamping bug with DE filter widths.
Provide functions to return the kernels from RendererCL to assist with diagnostics and debugging.
Prevent extra newline in EmberRender when only rendering a single image.
Add the ability to delete an ember at a given index in EmberFile.
Allow deleting/focusing ember in library tab with delete and enter keys.
Reorder some code in Fractorium.h to match the tabs order.
Add and call ClearFinalImages() to clear buffers in controller to fix bug where previous CPU render would be shown for a split second when switching from OpenCL back to CPU.
Refactor ember library pointer syncing to a function SyncPointers().
Add the ability to save ember Xmls to an unique automatically generated name after the first time the user has specified a name.
The command is intended to write XML output to stdout for piping into an xml file, but adds diagnostic information and warnings to the output, generating invalid XML.
