commit 4a938ef7136a89c828ebb16effe1bc5bea08b7d7
Author: Brian Paul <<a href="mailto:brianp@vmware.com">brianp@vmware.com</a>>

draw: add new debug code and comments in clip code template
In debug builds, set clipped vertex window coordinates to NaN values
to help debugging. Otherwise, we're just leaving the coordinate in clip
space and it's invalid to use it later expecting it to be a window coord.
