Before using depth buffer as texture, it needs to be decompressed
(tile pattern of db are different from one used for colorbuffer
like texture)

Introduce a new configuration option XMESA_STRICT_INVALIDATE to switch
between swapbuffers-based and glViewport-based buffer invalidation.
Default strict invalidate to false, ie glViewport-based invalidation,
aka ST_MANAGER_BROKEN_INVALIDATE.
This means we will not call XGetGeometry after every swapbuffers,
which allows swapbuffers to remain asynchronous. For apps running at
100fps with synchronous swapping, a 10% boost is typical. For gears,
I see closer to 20% speedup.
Note that the work of copying data on swapbuffers doesn't disappear -
this change just allows the X server to execute the PutImage
asynchronously without us effectively blocked until its completion.
This applies even to llvmpipe's threaded rasterization as the
swapbuffers operation was a large part of the serial component of an
llvmpipe frame.
The downside of this is correctness - applications which don't call
glViewport on window resizes will get incorrect rendering, unless
XMESA_STRICT_INVALIDATE is set.
The ultimate solution would be to have per-frame but asynchronous
invalidation. Xcb almost looks as if it could provide this, but the
API doesn't seem to quite be there.
This version should hopefully be much clearer and thus less likely
to be subtly broken.
Also fixes point sprites on nv40 and possibly some other bugs too.
My merge of Zhenyu's patch on top of my previous patches broke it by
my code expecting simd16 single write and Zhenyu's simd8 path being
disabled by mine. Merge the two for success.
The docs claim two conflicting things: One, that a scalar source is
supported. Two, source hstride must be 1 and width must be exec size.
So splat a constant argument out into a full reg to operate on, since
violating the second set of constraints is clearly failing.
The alternative here might be to do a 1-wide exec on a constant
argument for math1. It would probably save cycles too. But I'll
leave that for the glsl2-965 branch.
Fixes glsl-algebraic-div-one-2.shader_test.
dump_cpu is used only when DEBUG is defined.
Fixes the following GCC warning on builds without DEBUG defined.
util/u_cpu_detect.c:76: warning: 'debug_get_option_dump_cpu' defined but not used
Silence the following i686-apple-darwin10-gcc-4.2.1 warnings.
nv04_2d.c: In function 'nv04_region_copy_cpu':

i686-apple-darwin10-gcc-4.2.1 generated the following warning.
warning: 'score' may be used uninitialized in this function
GCC 4.4.3 on Linux didn't generate the above warning.
Partialy fix texturing from depth buffer, depth buffer is tiled
following different tile organisation that color buffer. This
properly set the tile type & array mode field of texture sampler
when sampling from db resource.
Add initial support to untiling buffer when transfering them,
it's kind of broken by corruption the vertex buffer of previous
draw.

This is valid input, and asserting here does causes the test suites that
verify this to crash.
Also, the assert was wrongly accepting the case
max_index == vert_info->count
which, IIUC, is the first vertex outside the buffer. Assuming the
vert_info->count is precise (which often is not the case).
The 'vec4[12] foo' style already worked, but the 'vec4 foo[12]' style
did not. Also, 'vec4[] foo' was wrongly accepted.
Fixes piglit test cases array-19.vert and array-21.vert.
May fix fd.o bug #29684 (or at least part of it).
