GPencil: Implement Holdout materials
This new feature allows to use the strokes as an eraser of any stroke below. This is very handy to open holes in filled areas.
After running some tests, we have decided to keep the additive effect of the holdout color. To get clean holdout areas, just move the color to black to remove any additive effect. To have additive effect can be used in situations like tint slightly a transparent window with blue to simulate the glass.
See T79878 for more details
