The swizzle used to generate the "original" value from the value
stored in the parameter array happens before the swizzle specified in
the instruction. This fixes problems seen in progs/vp/vp-tris with arl-*.txt.

Previously, the FOGC attribute contained the fragment fog coord, front/back-
face flag and the gl_PointCoord.xy values. Now each of those things are
separate fragment program attributes. This simplifies quite a few things in
Mesa and gallium.
Need to test i965 driver and fix up point coord handling in the gallium/draw
module...

When sampling a 2D shadow map we need 3 texcoord components, not 2.
The third component (distance from light source) is compared against
the texture sample to return the result (visible vs. occluded).
Also, enable proper handling of TGSI_TEXTURE_SHADOW targets in Mesa->TGSI
translation. There's a possibility for breakage in gallium drivers if
they fail to handle the TGSI_TEXTURE_SHADOW1D / TGSI_TEXTURE_SHADOW2D /
TGSI_TEXTURE_SHADOWRECT texture targets for TGSI_OPCODE_TEX/TXP instructions,
but that should be easy to fix.
With these changes, progs/demos/shadowtex.c renders properly again with
softpipe.

fixes texwrap
|
|
- set MAX_LOD properly
- min texel pitch is 8 texels
- emit old command buffer when re-initing base state
|
|
Configuration register values are now stored directly in that structure.

It was getting enabled anyway but without the entrypoints installed. Whoops.

Windows opengl32.dll calls glFinish prior to every swapbuffers, which
makes it pretty hard to get decent performance...
Work around by mapping finish to flush on PIPE_OS_WINDOWS. This is
conformant, though it might confuse poorly-written benchmarks which
attempt to measure a single event rather than figuring out the rate of
continuous processing.

Some apps enable scissor but set the rectangle to the dimensions of
the window. Don't let this force us onto a slower clear path.

The leading underscore is meaningful... This function is used by
_warning and _error functions as well as the more common
debug_printf().
debug_printf (without underscore) gets turned off when DEBUG is
disabled, but warning/error messages still use this function to get
their message out.

What was Z24S8 before is actually S8Z24, and what we had for Z16
is actually X8Z24. Now, we also have the REAL Z24S8 and I added
Z32_FLOAT as well; most of the formats need different tile_flags.

NOTE: we must not try to emit buffer relocations when
vtxbuf_nr is 0 but vtxelt_nr is not

Red and blue were interchanged in TIC.
Add border color and some formats.

|
The translation also needs to be inverted, and in bypass mode
the state tracker incorrectly assumes that Y = 0 = TOP, so we
need inversion there to; NDC clipping has to be deactivated
explicitly.

This makes texwrap look better.

Set the flat shading bit on the appropriate PS input
depending on the type of attribute it is. The VS output
and PS input routing should probably be made more dynamic
at some point. We may want to use semantic ids to make
it easier.

Release per screen DRI driver configs during screen destruction.

This breaks textures. We need to only set this bit for
attributes that that need flat shading.

This silences a compiler warning.

This isn't really tested yet as no drivers actually support this extension.

Passes the piglit asmparsertest shadow-0[123].txt tests and
progs/demos/shadowtex.
|

Require that GL_{ARB,EXT,NV}_texture_rectangle be supported before
allowing use of RECT texture target.

So totally awesome that _mesa_calloc has a different parameter
signature than calloc. Why do these libc wrappers still exist?!?
