-/* Polygon clip detection code
- *
- * The polygon clipping logic is based on the Cohen-Sutherland algorithm, but
- * only the off-screen detection logic is used to determine which polygon edges
- * are off-screen.
- *
- * In tri_clip, the following edges are checked as follows:
- *
- *  |\
- *  |  \
- *  |    \
- *  |      \
- *  |--------
- *
- * In quad_clip, the following edges are checked as follows:
- *
- *  |---------|
- *  | \     / |
- *  |   \ /   |
- *  |   / \   |
- *  | /     \ |
- *  |---------|
- *
- * The inner portion of the quad is checked, otherwise the quad will be
- * culled out if the camera faces right into it, where all four edges
- * are off-screen at once.
- *
