--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.
-Fix improper usage of rand() in cpow2, cpow3, hypertile1, hypertile3D1, hypertile3D2, juliac, juliaq.
-Fix program crashing during density filtering on some Nvidia cards.
-hypertile3D1 was wrong.
-Parsing phoenix_julia when coming from Apophysis was wrong.
-Density filtering was freezing on certain Nvidia cards.
--Code changes
-Optimize juliac, npolar.
-Add a new function Crand() which behaves like the legacy C rand() which returns an integer between 0 and 32766, inclusive.
-Use RandBit() in some places.
-Remove Zeps() from vignette, it's not needed.
-Restructure OpenCL code for density filtering such that it does not hang after being compiled on some Nvidia cards, such as the gtx 1660. Remove barriers from conditionals where possible.
-Show common folder locations such as documents, downloads, pictures in the sidebar in all file dialogs.
-Warning message about exceeding memory in final render dialog now suggests strips as the solution to the problem.
-Strips now has a tooltip explaining what it does.
-Allow more digits in the spinners on the color section the flame tab.
-Add manually adjustable size spinners in the final render dialog. Percentage scale and absolute size are fully synced.
-Default prefix in final render is now the filename when doing animations (coming from sequence section of the library tab).
-Changed the elliptic variation back to using a less precise version for float, and a more precise version for double. The last release had it always using double.
-New applied xaos table that shows a read-only view of actual weights by taking the base xform weights and multiplying them by the xaos values.
-New table in the xaos tab that gives a graphical representation of the probability that each xform is chosen, with and without xaos.
-Add button to transpose the xaos rows and columns.
-Add support for importing .chaos files from Chaotica.
--Pasting back to Chaotica will work for most, but not all, variations due to incompatible parameter names in some.
-Curves are now splines instead of Bezier. This adds compatibility with Chaotica, but breaks it for Apophysis. Xmls are still pastable, but the color curves will look different.
--The curve editor on the palette tab can now add points by clicking on the lines and remove points by clicking on the points themselves, just like Chaotica.
--Splines are saved in four new xml fields: overall_curve, red_curve, green_curve and blue_curve.
-Allow for specifying the percentage of a sub batch each thread should iterate through per kernel call when running with OpenCL. This gives a roughly 1% performance increase due to having to make less kernel calls while iterating.
--This field is present for interactive editing (where it's not very useful) and in the final render dialog.
--On the command line, this is specified as --sbpctth for EmberRender and EmberAnimate.
-Allow double clicking to toggle the supersample field in the flame tab between 1 and 2 for easily checking the effect of the field.
-When showing affine values as polar coordinates, show angles normalized to 360 to match Chaotica.
-Fuse Count spinner now toggles between 15 and 100 when double clicking for easily checking the effect of the field.
-Added field for limiting the range in the x and y direction that the initial points are chosen from.
-Added a field called K2 which is an alternative way to set brightness, ignored when zero.
--This has no effect for many variations, but hs a noticeable effect for some.
-Added new variations:

--Bug fixes:
-Bounds sign was flipped for x coordinate of world space when center was not zero.
-Right clicking and dragging spinner showed menu on mouse up, even if it was very far away.
-Text boxes for size in final render dialog were hard to type in. Same bug as xform weight used to be so fix the same way.
-Fix spelling to be plural in toggle color speed box.
-Stop using the blank user palette to generate flames. Either put colored palettes in it, or exclude it from randoms.
-Clicking the random palette button for a palette file with only one palette in it would freeze the program.
-Clicking none scale in final render did not re-render the preview.
-Use less precision on random xaos. No need for 12 decimal places.
-The term sub batch is overloaded in the options dialog. Change the naming and tooltip of those settings for cpu and opencl.
--Also made clear in the tooltip for the default opencl quality setting that the value is per device.
-The arrows spinner in palette editor appears like a read-only label. Made it look like a spinner.
-Fix border colors for various spin boxes and table headers in the style sheet. Requires reload.
-Fix a bug in the bwraps variation which would produce different results than Chaotica and Apophysis.
-Synth was allowed to be selected for random flame generation when using an Nvidia card but it shouldn't have been because Nvidia has a hard time compiling synth.
-A casting bug in the OpenCL kernels for log scaling and density filtering was preventing successful compilations on Intel iGPUs. Fixed even though we don't support anything other than AMD and Nvidia.
-Palette rotation (click and drag) position was not being reset when loading a new flame.
-When the xform circles were hidden, opening and closing the options dialog would improperly reshow them.
-Double click toggle was broken on integer spin boxes.
-Fixed tab order of some controls.
-Creating a palette from a jpg in the palette editor only produced a single color.
--Needed to package imageformats/qjpeg.dll with the Windows installer.
-The basic memory benchmark test flame was not really testing memory. Make it more spread out.
-Remove the temporal samples field from the flame tab, it was never used because it's only an animation parameter which is specified in the final render dialog or on the command line with EmberAnimate.
--Code changes:
-Add IsEmpty() to Palette to determine if a palette is all black.
-Attempt to avoid selecting a blank palette in PaletteList::GetRandomPalette().
-Add function ScanForChaosNodes() and some associated helper functions in XmlToEmber.
-Make variation param name correction be case insensitive in XmlToEmber.
-Report error when assigning a variation param value in XmlToEmber.
-Add SubBatchPercentPerThread() method to RendererCL.
-Override enterEvent() and leaveEvent() in DoubleSpinBox and SpinBox to prevent the context menu from showing up on right mouse up after already leaving the spinner.
-Filtering the mouse wheel event in TableWidget no longer appears to be needed. It was probably an old Qt bug that has been fixed.
-Gui/ember syncing code in the final render dialog needed to be reworked to accommodate absolute sizes.
--User changes
-dark.qss is now per-OS.
-Properly set/reload palette when coming from the palette editor. The latter must be done if they've modified the current palette even if they've clicked cancel.
--Bug fixes
-Make the following variations safer by using Zeps(): conic, bipolar, edisc, whorl, tan, csc, cot, tanh, sech, csch, coth, auger, bwraps, hypertile3d, hypertile3d1, ortho, poincare, rational3, barycentroid, sschecks, cscq, cschq, scry_3D, splitbrdr, hexcrop, nblur, crob.
-Fix bug enabling/disabling overwrite button in palette editor.
-Small optimization for gdoffs, use precalcAtanYX.
-Properly propagate z through circlesplit, cylinder2 and tile_log variations.
-Some values in truchet_fill could've been NaN.
--Code changes
-Make most installation files read only.
-Qualify many calls with std:: to ensure they're not colliding with glm::
-Use auto in more places.
-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.
-Remove some warnings about interpolation type on first and last flames.
--Code changes
-Make DE block size always be 16x16, this should help stability on some Nvidia cards. No changes for AMD cards since they were that size already.
-Since the block size is now so small, do not reduce it further when supersampling.
-Clean up some variable names and documentation around OpenCL DE to be more clear.
-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.
-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.
-Prevent user from saving stylesheet to default.qss, it's a special reserved filename.
--Code changes
-Generalize using the running sum output point inside of a variation for all cases: pre, reg and post.
-Allow for array variables in variations where the address of each element is stored in m_Params.
-Qualify all math functions with std::
-No longer use our own Clamp() in OpenCL, instead use the standard clamp().
-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 Simon Detheridge's name to the About Box.
--Bug fixes
-Fix bug in OpenCL atomic string, which is never used.
-Wrong hist and accum allocation size in RendererCL when using float-only buffers now.
-Move some kernel initialization to a place where it's done once per render, rather than on every interactive iter chunk.
--Code changes
-Make ConvertCarToRas() just assign to the member rather than return a struct.
-Make kernel string accessor functions in IterOpenCLKernelCreator, FinalAccumOpenCLKernelCreator and DEOpenCLKernelCreator be const and return a const string reference.
-Don't include atomic string unless locking on the GPU, which is never.
-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.
-Nvidia OpenCL compilation was broken for density filtering due to ambiguity in the arguments to min(). Fix it by casting.
-Put Nvidia block size in DE back to 24 where it used to be. Nvidia fails when it's 32.
-Fix misspelling of the word "Rendering" in failure messages in final render dialog.
-Put FillSummary() back when loading an ember.
-Properly disable add final xform button when a final xform is present.
Remove unnecessary resize() in Interpolate().
These are from Simon Detheridge's PR:
Set file name padding in EmberRender and
EmberAnimate based on the log10() of how many images are getting rendered, rather than hardcoding it to 5.
Use non-locale-imbued stream for writing filename in EmberAnimate.
Properly cast immediate float value used with pow() in density filter kernel.
--User Changes
Remove limit on the number of xforms allowable on the GPU. This was previously 21.

Make integer variation parameters use 4 decimal places in the variations list like all the others.
New build of the latest Qt to fix scroll bar drawing bug.
Prevent grid from showing as much when pressing control to increase a spinner's increment speed. Still shows sometimes, but better than before.
--Code Changes
Pass count and fuse to iterator as a structure now to allow for passing more params in the future.
Slightly different grid/block logic when running DE filtering on the GPU.
Attempt a different way of doing DE, but #define out because it ended up not being faster.
Restructure some things to allow for a variable length xforms buffer to be passed to the GPU.
Add sub batch size and fuse count as ember members, and remove them from the renderer classes.
Remove m_LastPass from Renderer. It should have been removed with passes.
Pass seeds as a buffer to the OpenCL iteration kernel, rather than a single seed that gets modified.
Slight optimization on CPU accum.
Use case statement instead of if/else for xform chosing in OpenCL for a 2% speedup on params with large numbers of xforms.
Add SizeOf() wrapper around sizeof(vec[0]) * vec.size().
Remove LogScaleSum() functions from the CPU and GPU because they're no longer used since passes were removed.
Make some OpenCLWrapper getters const.
Better ogranize RendererCL methods that return grid dimensions.
--User Changes
Size is no longer fixed to the window size.
Size scaling is done differently in the final render dialog. This fixes several bugs.
Remove Xml saving size from settings and options dialog, it no longer applies.
Final render can be broken into strips.
Set default save path to the desktop if none is found in the settings file.
Set default output size to 1920x1080 if none is found in the settings file.
--Bug Fixes
