994d1db079 i915: Let i915_program_error take a format string, and don't use _mesa_problem. 
It's misleading to report things like the program having too many native
instructions as a Mesa implementation error, when the program may just be
too big for the hardware.

bbae8791d1 i915: Use DEBUG_WM (like 965) for printing the fragment program out. 
This is nice when paired with INTEL_DEBUG=batch for debugging what's going
out to the hardware.

7db7ff878d mesa: merge the prog_src_register::NegateBase and NegateAbs fields 
There's really no need for two negation fields.  This came from the
GL_NV_fragment_program extension.  The new, unified Negate bitfield applies
after the absolute value step.

8d475822e6 mesa: rename, reorder FRAG_RESULT_x tokens 
s/FRAG_RESULT_DEPR/FRAG_RESULT_DEPTH/
s/FRAG_RESULT_COLR/FRAG_RESULT/COLOR/
Remove FRAG_RESULT_COLH (NV half-precision) output since we never used it.
Next, we might merge the COLOR and DATA outputs (COLOR0, COLOR1, etc).

129b6bc4e3 i915: separate the fog term from the specular color term. 
Previously fog parameter and specular color are packed into the
same dword. Note specular color should be packed in BGRA for device,
so if fog parameter and specular color all are present, fog parameter
will dirty the alpha term of specular color. This fixes rendering
issue when playing 'Yo Frankie' on 915/945.

700a77fb48 [915] Fix COS function using same plan as SIN. 
The previous COS function failed badly outside of [-pi/2, pi/2].

2551a5ee80 [915] Use a quartic term to improve the accuracy of SIN results. 
This is described in the link in the comment, and is the same technique that
r300 uses.

d98abcbef0 [915] Fix fp SIN function, and use a quadratic approximation instead of Taylor. 
The Taylor series notably fails at producing sin(pi) == 0, which leads to
discontinuity every 2*pi.  The quadratic gets us sin(pi) == 0 behavior, at the
expense of going from 2.4% THD with working Taylor series to 3.8% THD (easily
seen on comparative graphs of the two).  However, our previous implementation
was producing sin(pi) < -1 and worse, so any reasonable approximation is an
improvement.  This also fixes the repeating behavior, where the previous
implementation would repeat sin(x) for x>pi as sin(x % pi) and the opposite
for x < -pi.

d78f65cd6c Fix fragment program fog problems found with Glean. 
1. add PROGRAM_CONSTANT to switch() in src_vector().
2. use _mesa_append_fog_code() to handle fog options in i915ProgramStringNotify().
3. Re-enable some vertex attribute emit code that was previously disabled in i915ValidateFragmentProgram().

de99760bf3 Move stuff common to vertex/fragment_program into the base class, including: 
Instructions, InputsRead, OutputsWritten, and Parameters.
Also, added debug functions: _mesa_print_instruction(),
_mesa_print_program_parameters() and revamp _mesa_print_program().
