-Allow group dragging and floating of dock widgets.
--Note this has a bug where if tabls are grouped while floating, the tab position is placed on the bottom. It restores to the top when dropping on a dock location. I've filed a bug at qt.io
-Make some tables auto size to their contents because some text appeared obscured on Linux.
-The size of the xforms and palette tabs were preventing the main window from being resized to a small size on lower resolution monitors when docked. So rework scroll areas, minimum sizes and layouts to allow for a smaller main window.
-Support 4k monitors, and in general, properly scale any monitor that is not HD.
-Allow for a spatial filter of radius zero, which means do not use a spatial filter.
-Add new variations: concentric, cpow3, helicoid, helix, rand_cubes, sphereblur.
-Use a new method for computing elliptic which is more precise. Developed by Discord user Claude.
-Remove the 8 variation per xform limitation on the GPU.
-Allow for loading the last flame file on startup, rather than randoms.
-Use two different default quality values in the interactive renderer, one each for CPU and GPU.
-Creating linked xforms was using non-standard behavior. Make it match Apo and also support creating multiple linked xforms at once.
--Bug fixes
-No variations in an xform used to have the same behavior as a single linear variation with weight 1. While sensible, this breaks backward compatibility. No variations now sets the output point to zeroes.
-Prevent crashing the program when adjusting a value on the main window while a final render is in progress.
-The xaos table was inverted.
--Code changes
-Convert projects to Visual Studio 2017.
-Change bad vals from +- 1e10 to +-1e20.
-Reintroduce the symmetry tag in xforms for legacy support in programs that do not use color_speed.
-Compiler will not let us use default values in templated member functions anymore.
--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.
--Added panorama1 and panorama2 variations.
Bug fixes:
--crackle had a bug with Nvidia GPUs.
Code changes:
--crackle now uses real_t* for cache rather than real2. This is what was causing the bug.
--Make the local offsets array used in crackle a precalc since it's the same for all. This reduces register pressure.
--Get rid of all usages of real3, just to be safe since Nvidia doesn't like them.
--#define TOTAL_GLOBAL_SIZE_END in the OpenCL iteration kernel just for debugging purposes to see how large the parvars buffer is.
--Disallow the use of synth when randomly generating xforms if the user has an Nvidia device present on their system.
Code changes:
--Use some CPU defines in CL code.
--Change curves color scaling buffer to be 2^16 per channel instead of 2^17 which was probably overkill.
--Code in RendererClDevice::Init() to detect Nvidia was wrong even thought it technically worked.
--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.
--Blending is no longer needed in OpenGLWidget because of the new pixel type.
--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.
--Remove some unused functions.
-Attempt to fix several OpenCL build errors that were occurring on Mac.
--Code changes
-Improve the coloring code during final accum by getting rid of the last remnants of unnecessary scaling to 255 from flam3.
-Begin work of supporting 16bpc on the GPU.
