- * aliasing is requested it will (in the future) generate a single channel
- * (8bit) mask. If no anti aliasing is requested it will generate a 1-bit
- * mask in the stencil buffer. In the non anti-aliasing case, if the clip
- * mask can be represented as a rectangle then scissoring is used. In all
- * cases scissoring is used to bound the range of the clip mask.
