addScissor()

bool GrAppliedHardClip::addScissor ( const SkIRect &  irect, SkRect *  clippedDrawBounds  )

inline

Intersects the applied clip with the provided rect. Returns false if the draw became empty. 'clippedDrawBounds' will be intersected with 'irect'. This returns false if the clip becomes empty or the draw no longer intersects the clip. In either case the draw can be skipped.
