Hi Chris,

> in OGLSurfaceData so that it calls OGLPaints.isValid() to determine whether
> the given paint can be accelerated in the antialiased case.  If the paint
> can't be accelerated by OGL, we return null to indicate that validatePipe()
> should use a more general/slower path for rendering the paint via MaskBlit.
Ah yes there it is. Somehow I overlooked that.

Yes, thanks a lot - it works now as intended :)

Thanks a lot, Clemens
