Hi Clemens,
The antialiased case is handled in super.validatePipe() (in the
SurfaceData base class), which in turn calls getMaskFill(). We
override getMaskFill() 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. Does this help?

Hello,
I am currently trying to rewrite validatePipe using
OGLSurfaceData.validatePipe() as template,
however I am a bit confused about what happens in the antialiased
case, e.g. gradient as paint with antialiasing.
E.g. in my case I would like to fallback if the a RadialGradient with
focus!=center is set as paint, however OGLSurfaceData.validatePipe()
does only call isPaintValid() in the non-antialiased case, however it
seems to work fine there.
In my case the fallback is only hit when antialiasing is turned off.
Thanks for your patience, Clemens
