298187 - speed up canvas on X

Status: RESOLVED INVALID

(Core :: Graphics: Canvas2D, defect)

Description

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

This patch sets up canvas to use platform-native surfaces, and can provide a
significant speedup provided that the platform doesn't suck.  This patch also
adds native surface support for X11; win32 and quartz will come in a followup patch.

The one problem now, with X11, is that we're issuing X requests much faster than
normal X servers can process them, when the canvas is animating.  So, the X
server/actual rendering lags way behind the actual requests.  (Xglx has no
problems.)  This sort of sucks, but short of putting in an XSync after
FastPaint, I'm not sure what can be done about it.
