-Add two new variations, hyperbolic and hypershift2.
-Allow for animating final xforms.
-More detailed diagnostics when any action in the OpenCL renderer fails.
-Allow for creating an OpenCL renderer which does not share a texture with the main window, and instead manually copies its final output image from GPU to CPU then back to GPU.
--Bug fixes
-Text was not properly being copied out of the Info | Bounds text box.
--Code changes
-Remove Renderer::AccumulatorToFinalImage(v4F* pixels, size_t finalOffset), it's no longer needed or makes sense.
-Controllers no longer keep track of shared status, it's kept inside the renderers.
-Make getter functions in FractoriumOptionsDialog be public.
--Bug fixes
-Strips renders crashed.
-Better handling of large memory allocations by forcing a free of previous allocations.
-Final render dialog did not properly save last used extension setting.
-Density filtering progress bar in final render dialog did not update if only log scaling was being used.
--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.
-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

-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.

-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.
-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

-General cleanup.
-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 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.

-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().

--Add members to cache the values of global memory size and max allocation size.
-RendererCL.h/cpp:
--Redesign to accomodate multi-GPU.

--Remove DumpErrorReport() function, it's handled in the base.
--ClearBuffer(), ReadPoints(), WritePoints(), ReadHist() and WriteHist() now optionally take a device index as a parameter.
--MakeDmap() override and m_DmapCL member removed because it no longer applies since the histogram is always float since the last commit.

-EmberOptions.h:
--Remove --platform option, it's just sequential device number now with the --device option.

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

--Bug fixes
Prevent xform index flickering whenever changing the number of xforms.
--Code changes
Remove ForEach() wrappers and replace with range based for loops with auto.
Replace every regular for loop with a range based one where applicable. Note this doesn't work everywhere.
Make event filter application wide.
Add parameter to FillXforms() to specify the index to select, default 0.
Rename some scroll areas and layouts to names that make sense, rather than their designer defaults.
-If we change OpenCLWrapper to capture build log errors, we don't need to manually concat them in RendererCL because the overridden ErrorReport() function already concatenates the errors from both classes.
-Do not define T in OpenCL programs. We already have real_t to handle this.
-Do keep the casting to real_t. However this should not be necessary because there is a command line option to do this automatically which we already use: -cl-single-precision-constant. The only reason we do this is because the Apple OpenCL compiler does not follow the standard and obviously ignores this option. Absolutely awful.
-Fix a few improper casts in the CircleTrans1 and GlynnSim1 variations.
-Add an automated OpenCL program build tester to EmberTester, as well as a cast checker.
--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.

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.

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.

julia3d, julia3dz, loonie, mirror_x, mirror_y, mirror_z, rotate_x,
sinusoidal, spherical, spherical3d, stripes.
Unique filename on final render was completely broken.
Two severe OpenCL bugs. Random seeds were biased and fusing was being
reset too often leading to results that differ from the CPU.
Subtle, but sometimes severe bug in the setup of the xaos weights.
Use properly defined epsilon by getting the value from
std::numeric_limits, rather than hard coding 1e-6 or 1e-10.
Omit incorrect usage of epsilon everywhere. It should not be
automatically added to denominators. Rather, it should only be used if
the denominator is zero.
Force final render progress bars to 100 on completion. Sometimes they
didn't seem to make it there.
Make variation name and params comparisons be case insensitive.
--Code Changes
Make ForEach and FindIf wrappers around std::for_each and std::find_if.
