Description Eric Anholt 2004-08-13 23:08:58 UTC

Right now, xcompmgr and automatic update compositing are excruciatingly slow due
to source copies not being supported in XAA.  Attaching a diff to add support
for this using XAAScreenToScreenBitBlt to do the copy.  This brings xcompmgr -c
up to being quite tolerable performance-wise, and plain xcompmgr (and automatic
update as well, probably) is quite nice.
