Used in Quake3.

All gallium drivers should be able to support mixed-size color/depth/stencil
buffers.  If not, we'll need a new PIPE_CAP_ query.

This is handled entirely in core Mesa where the combiner state is converted
into a fragment program.

Since Ian's patch of a few weeks ago, we can enable all three variations
of two-sided stencil.  Update the state tracker to handle the extra back-
face state and turn on the EXT.

Note: there's a new Glean test for two-sided stencil now...

Fixes Cell regression.

add some more srgb texture formats, including compressed ones
various fixes relating to srgb formats

issues: the util code for generating mipmaps will not handle srgb formats
        correctly (would need to use a linear->srgb conversion shader)

Check for these caps in state tracker and enable corresponding GL extensions
if supported.

Update texture format selection code too.

The PIPE_CAP_S3TC token will be deprecated.

These are now per-screen functions, not per-context.
State tracker updated, code in drivers and p_context.h disabled.

The state tracker will call pipe->get_paramf(PIPE_CAP_BITMAP_TEXCOORD_BIAS)
to get a bias factor for adjusting the texcoords used in bitmap/drawpixels.
This allows us to compensate for small differences in rasterization from
one device to another.

So far max point size, line width, texture anistopy and lod bias.
