示例1: fs
/* This function currently always performs occlusion detection to
minimize paint regions. OpenGL precision requirements are no good
enough to guarantee that the results from using occlusion detection
is the same as without. It's likely not possible to see any
difference with most hardware but occlusion detection in the
transformed screen case should be made optional for those who do
see a difference. */
