Move edgeflag into the VERT_ATTRIB_SEVEN slot. This means that our
NV_vertex_program implementation has slightly incorrect aliasing
behaviour. I think this is reasonable given the simplification and
the fact that the mainstream ARB_vp continues to have the correct
behaviour.
- Removed all the old immediate, array and display list code.
- Remove references to the old array_cache module.
- Added a _tnl_draw_prims() entrypoint.
- Added a simplified data import facility for converting
non-floating point data as required.
Checkpoint commit - trivial/tri works.
fix (per-vertex) fog when using ARB_vp by incorporating fog factor computation into the vertex program (not yet fixed for swtnl). Simplify (and correct) the VTX_TCL_OUTPUT_VTXFMT handling when using vertex programs, turns out it's solely driven by the needs of the past-vertex stage of the pipeline, this should fix lockups with ill-specified applications using vertex programs (for instance applications enabling fog but not writing to fog coord output will now get (conformant) undefined results instead of lockups).
Emit cliprects in the userspace driver as required, rather than
passing them to the kernel. This works because all drawing commands
in the 965 driver are emitted with the lock held and the batchbuffer
is always flushed prior to releasing the lock. This allows multiple
cliprects to be dealt with, without replaying entire batchbuffers and
redundantly re-emitting state.
