which still happen somewhat frequently and were cluttering up my
fallback debugging output. x11perf says it's a major performance win in
those cases (though probably irrelevant), and it passes Xlib9.
through the whole CompositePicture stack and doing things like
computing damage over again. This is a sizeable win for text drawing
with a compmgr. Also avoid calling down into the server for dealing
with the scratch pixmap when we are able to do UploadToScreen
successfully and never need it.
down into an OutReverse and an Add. Turn off the fallback to software
glyphs when component alpha, now that we expect all (new) drivers to be
able to support it. Also, make Xephyr fall back in the CA Over case to
exercise this code. This speeds up my rgb24text and ls -lR in
gnome-terminal by a factor of 5.
and if they all have a maskFormat matching the format of the actual
glyphs If so, we can avoid the temporary pixmap for accumulating
glyphs, which reduces the number of operations done, and makes it
easier on the migration system. This fixes some significant performance
issues, particularly with subpixel antialiasing. Note that it does
increase the amount of damage computation which is done, so is not
always a win with a compositing manager running.
os-support/linux/lnx_KbdMap.c) we overrun the usefully-named global

This is fixed by changing the size of at2lnx. (David Woodhouse). Bug

lack of a better name. This one behaves somewhat between Greedy and
Always. It moves in if we can accelerate, unless the destination is
clean and shouldn't be kept in framebuffer according to the score, in
which case we migrate out (and force-migrate anything where migration
is free). This should help fix lack of acceleration for drivers without
UTS since removing exaAsyncPixmapGCOps, and has removed one performance
trap with Radeon I'd noticed. It is the new default.

video driver ABI needs to be bumped to 1.0. The rest of the ABI minor
versions were bumped to include the LoaderGetABIVersion function.
Add a DrawblePtr argument to the XV hooks. This allows drivers to determine
that the target window is redirected and draw to the appropriate place.
