-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.
-Switching between SP/DP didn't reselect the selected flame in the Library tab.
--Code changes
-Make all types concerning palettes be floats, including PaletteTableWidgetItem.

-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.

-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.

./
~/.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.

-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.

-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.

Allow for setting rendering thread priorities from the command line and final render dialog. Currently only implemented on Windows.
Show estimated time left on the final render dialog.
Sort palette list by name, instead of by index in the palette file.
Sorting can be flipped by clicking the column headers of the palette table.
--Code changes
Remove unnecessary connect() statement in Variations tab.
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.
--User changes
Thread image writing in EmberAnimate and when doing animation sequence in final render dialog.

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.
