Bug fix: Fix --resize-damage
- Fix --resize-damage. I forgot to shrink the painting region back when
actually copying to destination.
- Include extra pixels around the blur texture to avoid some possible
small issues, if --resize-damage is positive.
- Known issue: Line artifacts may still appear with --dbe (X Render
backend) or --glx-swap-method (GLX backend). I doubt if there's way to
fix this without very inefficient mechanisms.
