--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 buttons to copy and paste affine transforms.
-Show xform names on the column headers of the xaos table.
-Add a color-coded third column to the variations tree which shows any properties of each variation which are non-standard.
-Draw a transparent circle over hovered xforms.
-Change how xforms respond to dragging. Rotate only is now the default, and scale will only happen with shift.
--Optionally do scale and rotate when holding shift, via a setting in the options dialog.
--Bug fixes
-Snapping when dragging was wrong sometimes.
-The program would very rarely crash on startup due to some values being in an uninitialized state.
--Code changes
-Change almost every variation to use fma() in OpenCL when doing computations of the form a * b + c. This provides a slight speedup, mostly in double precision mode.
-Also apply fma() to affine calcs.
-Cleanup of OpenGL affine drawing code.
-Separate the concept of hovering and selecting xforms.
-Attempt to preserve xaos when adding xforms. Note this is not an exact copy, but just a preservation of some values based on position.
-Add some acceleration to the changing of spinner values when dragging the right mouse button to adjust.
-Make the pivot be the center of the viewable area when doing drag/rotate/scale with the right mouse button.
--Clamp minimum scale to 10
--Draw a line from the mouse position to the pivot.
-Keep a cache of the last added final xform with each flame so that it can be quickly added, removed, then added back for testing its effect.
--This is not saved with the xml file and is solely for interactive editing.
--Bug fixes
-File filtering in open and save dialogs were broken.
-Right clicking on integer spin boxes was causing the context menu to pop up, when it should be supressed just like double spin boxes.
-Deleting xforms was still broken.
--Code changes
-Refactor the code for adding and pasting xforms into a single global static function called AddXformsWithXaos().
-Convert OpenGL drawing code to use GLSL. Leave #define in until testing on multiple platforms is done.
-Always use double precision extension defines in OpenCL programs, even if DP is not selected. This is because elliptic now always uses DP.
-Add a palette editor.
-Add support for reading .ugr/.gradient/.gradients palette files.
-Allow toggling on spinners whose minimum value is not zero.
-Allow toggling display of image, affines and grid.
-Add new variations: cylinder2, circlesplit, tile_log, truchet_fill, waves2_radial.
--Bug fixes
-cpow2 was wrong.
-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.
-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.
-PaletteTableWidgetItem is no longer templated because all palettes are float.
-Include the source colors for user created gradients.
-Change parallel_for() calls to work with very old versions of TBB which are lingering on some systems.
-Split conditional out of accumulation loop on the CPU for better performance.
-Vectorize summing when doing density filter for better performance.
-Make all usage of palettes be of type float, double is pointless.
-Allow palettes to reside in multiple folders, while ensuring only one of each name is added.
-Refactor some palette path searching code.
-Make ReadFile() throw and catch an exception if the file operation fails.
-A little extra safety in foci and foci3D with a call to Zeps().
-Cast to (real_t) in the OpenCL string for the w variation, which was having trouble compiling on Mac.
-Fixing missing comma between paths in InitPaletteList().
-Move Xml and PaletteList classes into cpp to shorten build times when working on them.
-Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
-Change more NULL to nullptr.
-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".

-General cleanup.
-Add post_smartcrop.
--Bug fixes

-Wrong point assignment in hexaplay3D, hexnix3D.
-Improper Z assignment in rblur.

--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.

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.

Break RendererBase::MemoryRequired() into two functions, it and HistMemRequired() and return a tuple.
Add GlobalMemSize() and MaxAllocSize() functions in OpenCLWrapper.

Save each newly loaded ember in a file called "last.flame" in the executable folder. This will help diagnose crashes that occur when switching embers.
Use nullptr instead of NULL in the Fractorium project. It had previously been done in all other places.
