-Further work on the About box.
--Change qss files to make the text box in the About box be the same color as the one in the style dialog, so the link text is easier to see.
--This requires reloading the qss file.
--Bug fixes
-Pre/post assign method was wrong for Sphereblur, Concentric, RandCubes and PixelFlow.
--Code changes
-Make Hypershift2 use MwcNextRange() instead of MwcNext() %.
-Add m_HasPre to Xform similar to m_HasPost, to skip application of the affine if it's the ID matrix (in this case just assign the input x and y points). This gives a 5% speedup.
--User changes
Use actual strips count when computing memory requirements in the final render dialog.
Output CL_DEVICE_ADDRESS_BITS when passing --openclinfo to command line programs.
Warn if single/total allocations are greater than the max allowed for OpenCL in the final render dialog.
Make about box properly sized for different fonts.
Dock widget is slightly resizable now.
Center scroll area when loading a new ember.
--Bug Fixes
Fix bad values left in an ember when a render with strips > 1 fails in the final render dialog.
Fix incorrect calculation in dc_cube variation when using OpenCL.
--Code Changes
Major work to get it running on Linux.
Migrate from QGLWidget to QOpenGLWidget.
Delayed init due to QOpenGLWidget.
Break RendererBase::MemoryRequired() into two functions, it and HistMemRequired() and return a tuple.
Add GlobalMemSize() and MaxAllocSize() functions in OpenCLWrapper.
Change CHOOSE_XFORM_GRAIN to be 16384, so we can & with 16383 instead of using modulo when selecting an xform. This results in a 9% speed increase on the CPU.
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.
