Canvas Clip performance

Hi guys,

I've noticed that clipping performance (Canvas GraphicsContext) is
extremely bad on an Intel HD graphics chip. One rectangular clip is fine,
anything beyond that, or a spherical clip shape, will bring the framerate
to its knees.

I notice no performance difference on my GeForce system, but on the
integrated chip my application is basically insufferable.

The same thing performed with Java2D experiences no performance issues on
neither system.

Any ideas?
