commit 128cd03eecacc6d5c5903d59a11966dcf3697bf1

Fix miComputeCompositeRegion() to follow new clip rules.
Ignore the hierarchy clip, and always apply any client clip after
transformation and repeating.

commit e9aa61e9f0d663d5b34a397b943b4d1df44e873d
Author: Søren Sandmann Pedersen <sandmann at redhat.com>

Fix clipping when windows are used as sources
The new clipping rules:
- client clips happen after transformation
- pixels unavailable due to the hierarchy are undefined
The first one is implemented in pixman; the second one is realized by
making a copy of window sources (to prevent out-of-bounds access).
