This was introduced with commit 92d7ed8a20.
It causes rendering of stray polygons (with sw rendering at least) when
running the OGL Distilled / Picking demo (click on an object).
This needs additional debugging to fix/restore.
Found one suspect thing: in _tnl_draw_prims() there's some mixed signed/
unsigned arithmetic/comparing at line 422 that may be incorrect.
If the 'end' index is out of bounds issue a warning as before. But instead
of just no-op'ing the draw call, examine the actual array indices to see
if they're OK. If the max array index is out of bounds, issue another
warning and no-op the draw call. Otherwise, draw normally. This is a
debug build-only feature since it could impact performance.
This "fixes" the missing torus in the OGL Distilled / Picking demo.
- max texture size is 8k, but mesa doesn't support
that at the moment.
- attempt to set shader limits to what the hw actually
supports
- clean up some old r300 cruft
- no need to explicitly disable irqs. This is fixed
in the drm now.

This causes gcc to issue warnings when format parameters do not match up
with the format string in calls to debug_printf.

- MUL_LIT is ALU.Trans instruction
- some Trans instructions can take 3 arguments
- don't clobber dst.x, use dst.z as temp, it'll get written correct
value in last insn
- respect source swizzles
The handling is a bit inefficient, unfortunately, but I don't want to make
any intrusive changes for Mesa 7.6.

Since commit 2921a2555d ('intel: Deassociated
drawables from private context struct in intelUnbindContext'),
intel->driDrawable may be NULL in intel_flush().
Do-while makes macro safe to be used with if and for constructions.
Also remove __LINE__ macro from variable name because scope is local to macro anyway.
Normally, the mesa/st would create a fake front buffer out of a
client-allocated surface.
In the DRI setting, however, st/dri provides a front buffer surface which is
created and maintained by the X server. Prefer to use this surface instead,
so that front buffer rendering and reading works correctly.

We obviously need to move the code addr register backwards because their may
be overlap.
This bug affected in particular the Compiz water plugin.
