WebCore uses the platform's graphics library, if that graphics library has bad
perf in some cases it can easily cause all sorts of badness.  I'm unsure
whether the solution should be to get Qt to fix this issue (presumably it's a
problem in their graphics library) or fix it in WebCore itself (which may
negatively impact performance of other platforms)

Maybe this logic should be in GrpahicsContextQt?
