  values which point to either the current client-supplied
  program if enabled, or otherwise to the current mesa-internal
  program.  Thus this program is always the correct one for
  the current state, providing that the mesa flags to turn on
  automatic generation are enabled.

  program changes.  This is cleaner than trying to code all the

complicated by the fact that spans are broken (Bug #1615), but some appear to be
real bugs.  However, while spans remain broken, I found that visual results were
better by avoiding fallbacks rather than avoiding just a broken stencil
implementation.  Note that this required changing the depth spans at 24+8bpp
into read-modify-write cycles.  It would be nicer as a single write with
a mask, but the kernel span blits turn off masking.

not respecting the coords (or perhaps interpreting them differently?) in my
