--User changes
 -Make all fonts be MS Shell Dlg 2. This will require reloading dark.qss if users are already using it.
 -Limit size of the left side of the palette editor.
 -Disable create from image buttons in the palette editor when working on a fixed palette.

--Bug fixes
 -The following variations were wrong: coshq, cothq.
 -During iteration, the color index could become nan if all xform color speeds were negative. This could lead to bad results on the GPU. Fix to check for nan. Minimal speed difference.

--Code changes
 -Make the following variations safer by using Zeps(): sinq, sinhq, secq, sechq, tanq, tanhq, cosq, coshq, cotq, cothq, cscq, cschq, estiq.
 -Always pass -cl-no-signed-zeros -cl-denorms-are-zero to kernel compiles for both single and double.
 -Flush all denormals to zero for all executable programs. This will likely lead to a speedup for badly behaving programs.
