Slimming Paint (a.k.a. Redesigning Painting and Compositing)

To get a sense of the extent of this rewrite, one side-effect will be the deletion of the code in core/rendering/compositing/.


SlimmingPaintV1 - paint using display items (Status: launched in M45)

SlimmingPaintInvalidation - rewrite of paint invalidation using display items, property trees introduced in blink (Status: launched in M58)

SlimmingPaintV175 - uses property trees for painting in blink, introduces paint chunks, uses paint chunks for raster invalidation (Status: launched in M67)
