-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.
