2009-04-27mesa/st: fix incorrect face, level in compress_with_blitKeith Whitwell
We were incorrectly applying the destination texture face and level when requesting a transfer to the temporary texture, which has only one face and level. This would obviously cause problems uploading to compressed cube and mipmap textures.

2009-04-22st: also check _NEW_PROGRAM flag for vertex shader constant buffersBrian Paul
This is a follow-on to commit c1a3b852807fb160f0cd246c1364b7336b4b947e. Note that (at this time) wherever _NEW_PROGRAM_CONSTANTS is set we're still setting _NEW_PROGRAM so this won't really make any difference (for now).

2009-04-21st: play it safe for now and check _NEW_PROGRAM for shader const buffer atomBrian Paul
When a new program is bound but no constants are updated we still need to update the Gallium const buffer.
2009-04-21st: use the static atoms[] array directlyBrian Paul
We can simplify this now that we no longer have any dynamic atoms.
2009-04-21st: do away with dynamic state atom for const buffersBrian Paul
Just use the new _NEW_PROGRAM_CONSTANTS flag instead.

2009-04-20st: assert on pipe_buffer_create failureKeith Whitwell
This needs a proper fix to propogate the out-of-memory condition back up to Mesa and the app as a GL error. Until then, at least catch the problem at its source.

2009-04-17gallium: Create OGL state tracker wrappers for various CPU access operations.Thomas Hellstrom
There are two usage types of buffer CPU accesses: One where we try to use the buffer contents for multiple draw commands in a batch. (batch := sequence of commands that are flushed together), like incrementally adding bitmaps to a bitmap texture that is reallocated on flush. And one where we assume we can safely overwrite the old buffer contexts, like glTexSubImage. In this case we need to make sure all old drawing commands referencing the buffer are flushed before we map the buffer. This is easily forgotten. Add wrappers for the most common of these operations. The first type is prefixed with "st_no_flush" and the second type is prefixed with "st_cond_flush", where "cond" indicates that we attmpt to only flush if there is indeed unflushed draw commands referencing the buffer. Prefixed functions are screen::get_tex_transfer pipe_buffer_write pipe_buffer_read pipe_buffer_map Please use the wrappers whenever possible.

2009-04-14mesa: merge the prog_src_register::NegateBase and NegateAbs fieldsBrian Paul
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.

2009-04-10gallium: remove pipe_texture::compressed fieldBrian Paul
The format field encodes compressed vs. uncompressed already. We can easily check if a texture is compressed with pf_is_compressed(texture->format).

2009-04-09st: remove unneeded "is compressed" checkBrian Paul
The format indicates compressed vs. uncompressed.

We can determine if the texture is compressed by checking the format.

This is a (partial) backport of the signed texture format support in OGL 3.1. Since it wasn't promoted from an existing extension roll our own.
