Detailed Description

GrHardClip never uses coverage FPs. It can only enforce the clip using the already-existing stencil buffer contents and/or fixed-function state like scissor. Always aliased if MSAA is off.

apply()

virtual Effect GrHardClip::apply ( GrAppliedHardClip *  out, SkIRect *  bounds  ) const

pure virtual

Sets the appropriate hardware state modifications on GrAppliedHardClip that will implement the clip. On input 'bounds' is a conservative bounds of the draw that is to be clipped. After return 'bounds' has been intersected with a conservative bounds of the clip.

Implemented in GrFixedClip, and skgpu::ganesh::StencilClip.
