Git commit e488caa31049bfff784f57fa79903df07e02aa1f by Dmitry Kazakov.
Committed on 28/08/2020 at 21:14.
Pushed by dkazakov into branch 'krita/4.3'.
Fix Divide, Vivid Light and Parallel blending modes handle negative layer
colors
Sometimes, when converting RGBAF32<->LabAF32 colorspaces, LCMS may
generate pixels with "slightly negative" values, like -1e-7. The
mentioned blending modes couldn't handle that correclty, because
they only checked for zero'ness.
Now before doing a division operation we:
1) check if the value isn't too small
2) check it the value is positive
NOTE: there are still a lot of blendign modes from "Binary" section
that still don't handle that correctly. But, speaking truly, I
don't think we should actually enable these blending modes for
F32 color spaces :)
