it's not that big of a deal in more normal apps, and axes a good bit of code.
And I assume that t_vertex will only get faster. Removes ~43k from compiled
binary.
Tested with: quake3, ut, ipers, texcyl, chromium, tuxracer, neverball (kinda)
scratch. There were just too many cut-and-paste errors in the code,
and it was too hard to follow.
This fixes Mesa bugzilla #1508. #1509 is probably also fixed, but
I'd like to do some more testing before I close that particular bug.
Additionally, this cuts almost 4,600 lines of code from the driver.
state with a function. This function sets the bits correctly. Did some
trivial refactoring on some of the GL_COMBINE code.
First pass at replacing classic texture environments with GL_COMBINE.
This is controlled by the EXPERIMENTAL_COMBINE_MODE define.
for GL_ARB_texture_mirrored_repeat. Enabled GL_NV_blend_square. It has
always actually been supported. Removed redundant EXT versions of ARB
extension strings.
state in a ready-to-emit cmdbuf, which avoids the issue Nicolai Haehnle reported
where the check() could return differently during backup-and-emit than it should
have if it were called at the right time. Move the lit emission before most of
the TCL state emission on r200, which fixes neverball issues.
Tested with: r100/r200 with neverball, tuxracer, chromium, quake3, ipers
a new cmdbuf, to ensure that state wasn't lost across UNLOCK/LOCK pairs (in the
case of context switching). This was rather inefficient. Instead, after
flushing a cmdbuf, mark the state as needing to be saved on unlock. Then, at
the beginning of flushing a cmdbuf, if we actually have lost the context, go
back and emit a new cmdbuf with the full set of state, before continuing with
the cmdbuf flush. Provides a 10-15% improvement in ipers performance in my
tests, along with other apps.

emitted in a fixed order these days, and go with a simpler single list.

lifted from the i915 side. i830 will now report version 1.3! Hurrah!
With the exception of GL_EXT_texture_compression_s3tc, the i830 driver
now supports all the extensions that its Windows counterpart supports.
