 /**
  * Gr uses the stencil buffer to implement complex clipping inside the
  * GrDrawTarget class. The GrDrawTarget makes a subset of the stencil buffer
  * bits available for other uses by external code (clients). Client code can
  * modify these bits. GrDrawTarget will ignore ref, mask, and writemask bits
  * provided by clients that overlap the bits used to implement clipping.
  *
  * When code outside the GrDrawTarget class uses the stencil buffer the contract
  * is as follows:
