Bugzilla #4616:

Browse source 
- Merge various fb/ bits of COMPOSITE support from xserver, which weren't
    necessary before due to cw hiding the issues. Fixes offset calculations
    for a number of operations, and may pull some fixes that cairo has
    wanted for XAA as well.
- Add a new call, miDisableCompositeWrapper(), which a DDX can call to keep
    cw from getting initialized from the damage code. While it would be
    cleaner to have each DDX initialize it if it needs it, we don't have
    control over all of them (e.g. nvidia).
- Use the miDisableCompositeWrapper() to keep cw from getting set up for
    screens using EXA, because EXA is already aware of composite. Avoiding
    cw improved performance 0-35% on operations tested by ajax in x11perf.
