E.g. when mapping buffers could flush CS or cause waiting
for a busy buffer.
The side effect of this is it also fixes progs/demos/arbocclude however
a separate fix should be proposed to address this issue in other cases
it might occur.
Now that transfers are context objects their sideeffects must happen in
order when used by the state tracker, but that synchronization must be
bypassed when used inside the driver, or it would cause infinite
recursion.
Allows compiz to work in depth 16.
The DRI2 getBuffersWithFormat hook is only required for 16/32 bit depth
buffers, for colour buffers the only requirement is that the format matches
the drawable depth, which we can't check here.
(cherry picked from commit c50477c255)
The mapping for vertex_array_bgra:
(gl -> st -> translate)
GL_RGBA -> PIPE_FORMAT_R8G8B8A8 (RGBA) -> no swizzle (XYZW)
GL_BGRA -> PIPE_FORMAT_A8R8G8B8 (ARGB) -> ZYXW (BGRA again??)
Iẗ́'s pretty clear that PIPE_FORMAT_A8R8G8B8 here is wrong. This commit
fixes the pipe format and removes obvious workarounds in util/translate.
Tested with: softpipe, llvmpipe, r300g.

The stride depends on the mipmap level. Rename to row_stride to
distinguish from img_stride for 3D textures.
Fixes incorrect texel addressing in small mipmap levels.
don't enable APPLE_client_storage, TDFX_texture_compression_FXT1,
EXT_cull_vertex, NV_vertex_program, NV_vertex_program1_1 -
the latter two might work somewhat with some luck.
Also don't enable ARB_imaging.
There was very little use for this beyond permitting the
pipe_context::tex_transfer_destroy() function to omit the pipe_context
argument.
This change adds the pipe_context argument into tex_transfer_destroy()
so that it looks like other pipe_context functions, and removes the
pipe_context pointer from pipe_transfer.
We could use single 1 bit conditions for scalar masks, but a lot of code
expects masks. The compiler easily optimzes away masks
extensions/truncations so consistency is preferable.
We can revisit this when LLVM backends have more support for vector
conditions.
