Detailed Description

SIMD optimized code to clip a triangle or quadrilateral against a plane in GLSL.

Design goals are to:

1. maximize coherence (to keep all threads in a warp active for scalar ALUs) by quickly reducing to a small set of common cases,
2. maximize vector instructions (for vector ALUs)

1. minimize peak register count (to enable a large number of simultaneous threads), and
2. avoid non-constant array indexing (which expands to a huge set of branches on many GPUs)
