Alan,
I studied your mods heavily for performance considerations, and
the clipping work that you added is basically the same, but placed one procedure
higher, and removed from the lowest level line draw code. Thus, the extra
overhead is only one extra procedure call. Don't you agree?
Also, there needs to be a mid-level procedure anyway, as the nanogui
stuff won't work with out some routines that swap x1/x2 if the line segment is
right-to-left, rather than left-to-right, etc. I had to add this to get nanogui to run
with the sample programs.
