-Fix OpenCL compilation bugs in a few variations.
--Code changes
-Pre/post variations are now checked for precalcs when creating the OpenCL kernel code.
-Change some enumeration t
-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.
-No longer constrain pitch, yaw or depth spinners to -180 - 180.
--Bug fixes
-Properly set color index on padded xforms.
-Adding a padding final xform included a linear variation with a weight of zero to not appear empty. Made it have a weight of 1.
-Always write animate tag on final xform when saving to Xml.
-Motion was being applied to the wrong flame in SheepTools::Edge(), so apply it to the correct one.
-Prevent divide by zero when normalizing variation weights.
-Was accidentally adding the placeholder value of -9999 for motion_offset to varation weights and parameters when applying motion. Set to zero if no value present.
-Clamp flame rotation values to -180 - 180 when reading a flame from Xml.
-Events were not properly wired for user changes in the random rotations per blend controls in the sequencer.
-Fix major UI bugs with sequencer min/max random controls which made it nearly impossible to hand type values.
-Values from rotations per blend and rotations per blend max were not being saved to file between program runs.
-Checking animate for an xform was not applied to all flames even if Apply All was checked.
-Changing interpolation type, temporal filter width, temporal type, and affine interpolation type were not actually saving to the flame when changed.
-Grid on the main window was not being drawn at the right scale initially due to some OpenGL initialization occurring in the wrong order.
-Severe bugs in sequence generation code:
--Improperly detected padding xforms.
--When looking for specific variations during xform aligning, only presence was detected, when it should have been presence plus a weight greater than zero.
--When adding specific variations during xform aligning, must first remove any variations of that type.
--Two variables were unsigned when they should have been signed. This prevented large blocks of code from ever executing.
--When interpolating affines, an EPS that was too small was used, causing affine values to interpolate incorrectly. Instead use 1e-10 to ensure results equal to flam3.
--Code changes
-Modify FractoriumEmberController::UpdateXform() to pass the selected xform index as well as the absolute index to func().
--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.

--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.

--User changes
-Add support for adjusting xform color indices in the palette editor. Fixed palettes can now be displayed there, but they will have no color arrows as they are not editable.
-Add support for independent dimension scaling in the EmberRender and EmberAnimate programs to bring them in line with the final render dialog Fractorium.
--Bug fixes
-File paths with a space in them did not work in the command line programs.
-Any Xml file in the search paths would erroneously be treated as a palette file.
--Code changes
-Change some for loops to while loops when iterating through xforms.
-Allow FractoriumEmberController<T>::UpdateXform() to be able to apply the action to an xform at a specific index.
-Remove old code blocks build files that were never used.
-Make GetPath() return empty string if no path is present in the passed in file path.

-Palettes with rapid changes in color would produce slightly different outputs from Apo/Chaotica. This was due to a long standing bug from flam3.
-Use exec() on Apple and show() on all other OSes for dialog boxes.
-Trying to render a sequence with no frames would crash.
-Selecting multiple xforms and rotating them would produce the wrong rotation.
-Better handling when parsing flames using different encoding, such as unicode and UTF-8.

-Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
-Change more NULL to nullptr.
--User changes

-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

--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.

--Code changes
-Wrap EmberCommon.h in a namespace called EmberCommon.
-Move FormatName() from EmberGenome to EmberCommon.h/cpp

-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.
-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

-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

--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.
-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.
-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 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.
-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 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.

-Make info tab tree always expanded.
--Bug fixes
-Make precalcs for all hypertile variations safer by using Zeps() for denominators.

-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.

--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.

DESTDIR = ../../../Bin/debug
}
QMAKE_POST_LINK += $$quote(cp --update ../../../Data/flam3-palettes.xml $${DESTDIR}$$escape_expand(\n\t))

-AboutDialog.ui: Another futile attempt to make it look correct on Linux.
-FinalRenderDialog.h/cpp:

-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.
Make xaos display a matrix rather than a single column. This will be moved out into its own tab since it's no longer xform dependent, but that will be in a future commit.
Remove xaos from/to button since it's no longer applicable.
Add test function to Isaac to return just one random byte. Might be used in the future.
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.
--User Changes
Remove limit on the number of xforms allowable on the GPU. This was previously 21.
Show actual strips count to be used in parens outside of user specified strips count on final render dialog.
Allow for adjustment of iteration depth and fuse count per ember and save/read these values with the xml.
Iteration optimizations on both CPU and GPU.
Automatically adjust default quality spinner value when using CPU/GPU to 10/30, respectively.
--Bug Fixes
Fix severe randomization bug with OpenCL.
Fix undo list off by one error when doing a new edit anywhere but the end of the undo list.
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
Better memory size reporting in final render dialog.
--Code Changes
Migrate to C++11, Qt 5.3.1, and Visual Studio 2013.
Change most instances of unsigned int to size_t, and int to intmax_t.
Add m_OrigPixPerUnit and m_ScaleType to Ember for scaling purposes.
Replace some sprintf_s() calls in XmlToEmber with ostringstream.
Move more non-templated members into RendererBase.
Add CopyVec() overload that takes a per element function pointer.
Add vector Memset().
Replace '&' with '+' instead of "&" in XmlToEmber for much faster parsing.
Break strips rendering out into EmberCommon and call from EmberRender and Fractorium.
Make AddAndWriteBuffer() just call WriteBuffer().
Make AddAndWriteImage() delete the existing image first before replacing it.
Add SetOutputTexture() to RendererCL to support making new textures in response to resize events.
Remove multiple return statements in RendererCL, and replace with a bool that tracks results.
Add ToDouble(), MakeEnd(), ToString() and Exists() wrappers in Fractorium.
Add Size() wrapper in EmberFile.
Make QString function arguments const QString&, and string with const string&.
Make ShowCritical() wrapper for invoking a message box from another thread.
Add combo box to TwoButtonWidget and rename.
