Fixes assertion failure with texture swizzling in the GLSL path when
it's triggered (such as gen6 FF or ARB_fp shadow comparisons).
Fixes:
texdepth
texSwizzle
fp1-DST test
fp1-LIT test 3
Also fixup code comment to reflect that the GPU requires DWORD
alignment, but in this case does not actually pass the value "in
DWORDs" as I previously stated.
This reverts commit 76360d6abc. On
second thought, it turned out that sync objects also used the
wait_rendering API like this, and would need the same treatment, and
so wait_rendering itself is fixed in libdrm now.
We were asking for a wait to GTT read (all GPU rendering to it
complete), instead of asking for all GPU reading from it to be
complete. Prevents swapbuffers-based apps from running away with
rendering, and produces a better input experience.
For some reason I though we needed the _DISCARD flag to avoid
readbacks, which isn't true at all. Now write operations should
pipeline properly, gives a good speedup to demos/tunnel.
When linked with certain builds of libstdc++, it appears like powf is resolved
by a symbol in that library. Other builds of libstdc++ doesn't contain that
symbol resulting in a linker / loader error. Optionally
resolve that symbol and replace it with calls to logf and expf.

Fixes this GCC warning.
graw.h:93: warning: 'struct pipe_surface' declared inside parameter list
graw.h:93: warning: its scope is only this definition or declaration,
which is probably not what you want
A call to radeon_prepare_render() at the beginning of draw
operations was placed too deep in the call chain,
inside r300RunRenderPrimitive(), instead of
r300DrawPrims() where it belongs. This leads to
emission of stale target color renderbuffer into the cs if
bufferswaps via page-flipping are used, and thereby causes
massive rendering corruption due to unsynchronized
rendering into the active frontbuffer.
This patch fixes such problems for use with the
upcoming radeon page-flipping patches.

The width of the 2D blits used to copy the data is defined as a 16-bit
signed integer, but the pitch must be DWORD aligned. Limit to an integral
number of DWORDs, (1 << 15 - 4) rather than (1 << 15 -1).
Fixes corruption to data uploaded with glBufferSubData.

Allows applications to dump surfaces to file without
referencing gallium/auxiliary entry points statically.
Existing test apps have been modified such that
they save the contents of the fronbuffer only
when the `-o' option's specified.
