Since the stencil buffer is interleaved, the generic Mesa renderbuffer

I know you had done this with handwritten functions at one point, rather than
using stenciltmp.h. Why the change, if you don't
mind me asking? Either way is fine, of course.
Before finalizing the patch, I decided to thoroughly inspect the
macros-from-hell one more time, just to make sure that I didn't
miss some necessary magic they did. And, I did miss some magic. The macros
perform clipping on the span ranges.
Rather than try to duplicate (likely incorrectly) the macros' clipping logic, I
just bit the bullet and used them.
Ah. :( Yeah, that seems wise.
