same width/height for front-buffer drawing. The fakexa code then uses
this extra space for offscreen pixmaps. Note that this tones down the
absurdity of fakexa's offscreen pixmap alignment requirements (odd
alignment is too weird, so stick with "24", which is still strange but
exists out there). It also fixes a couple of bugs in the fakexa
implementation revealed by using offscreen pixmaps.
