Patch to reduce resize flickering
Resizing windows in rootless mode causes them to flicker very badly. This is
because the default WM_ERASEBKGND handling occurs, which erases the entire
invalidated area with the default (white) brush, pointlessly, before the entire
invalidated area is bitblt'ed from the shadow framebuffer.
Attached patch causes WM_ERASEBKGND handling to be skippped.
Patch in the queue for 1.5.3-7.
Pushed in 1.5.3-7; closing.
