示例1:
/*
===================
R_ClipLineToLight
If neither point is clearly behind the clipping
plane, the edge will be passed unmodified. A sil edge that
is on a border plane must be drawn.
If one point is clearly clipped by the plane and the
other point is on the plane, it will be completely removed.
