Changes in v3:
- Renumber caps to accomodate caps to add to master in the meantime
- Document caps
- Add unsupported caps to *_screen.c too
Changes in v2:
- Split for properties patch
- Use positive caps instead of negative caps
This adds 4 caps to indicate support of each of the fragment coord
conventions.
All drivers are also modifed to add the appropriate caps.
Some drivers were incorrectly using non-Gallium-default conventions,
and caps for them have them set so that they will behave correctly
after the later state tracker patches.
This drivers are softpipe/llvmpipe (uses integer rather than half
integer) and pre-nv50 Nouveau (uses lower left rather than upper left).
Other drivers might be broken. With this patchset, fixing them is
only a matter of exposing the appropriate caps that match the behavior
of the existing code.
Drivers are encouraged to support all conventions themselves for better
performance, and this feature is added to softpipe in a later patch.
This patch removes PIPE_TEX_FILTER_ANISO.
Anisotropic filtering is enabled if and only if max_anisotropy > 1.0.
Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be
considered equivalent, and meaning to turn off anisotropic filtering.
This approach has the small drawback of eliminating the possibility of
enabling anisotropic filter on either minification or magnification
separately, which Radeon hardware seems to support, is currently
support by Gallium but not exposed to OpenGL. If this is actually
useful it could be handled by splitting max_anisotropy in two values
and adding an appropriate OpenGL extension.
NOTE: some fiddling & reformatting by keithw to get this patch to
apply. Hopefully nothing broken in the process.
this fixes a crash with the xorg state tracker, however it then locks
up the GPU once rendering is enabled but at least it doesn't crash.

Revert to fixed-layout surface binding table -- it's probably the best
way to do this. Pass sampler and texture numbers separately even
though we're always keeping them the same at present.
