  [TexMap] Incorrect damage information produced for animations with blur
https://bugs.webkit.org/show_bug.cgi?id=277484

Reviewed by Nikolas Zimmermann.

This change:
- adds a mechanism to collect damage from replica/filter/mask's
  overlap regions
- makes the damage being propagated always when dirty region changes
- removes two workarounds invalidating whole layer in some cases
so that damage from ongoing animations is colleced correctly now.
