The blend_quad function clobbers the actual render target color/alpha
values while applying the destination blend factor, which results in
restoring the wrong value during the masking stage for write-disabled
channels.

Not sure how I computed these, but they were wrong (which explains why
bumping the polynomial order before never improved precision).
This allows to pass the EXP test cases of PSPrecision/VSPrecision DCTs.
Add an iteration step, which makes rqsqrt precision go from 12bits to
24, and fixes RSQ/NRM test case of PSPrecision/VSPrevision DCTs.
There are no uses of this function outside shader translation.
This is an alternative to the draw module's polygon stipple stage.
The softpipe implementation here is just a test. The advantange of
using the new polygon stipple utility module (with other drivers)
is we can avoid software vertex processing in the draw module and
get much better performance.
Polygon stipple doesn't require special vertex processing like
the other draw module stage.
u_vbuf_upload_buffers modifies the buffer offsets. If they are not
restored, and any of the vertex formats is not supported natively, the
next u_vbuf_mgr_draw_begin call will translate the vertex buffers with
incorrect buffer offsets.
LLVM 3.0svn introduced a new type system. It defines a new way to create
named structs and removes the (now not needed) LLVMInvalidateStructLayout
function. See revision 134829 of LLVM.

These happen to work because their values are the same as the equivalent
PIPE_TRANSFER_* flags, but it's still misleading.

The following resolves the build issues and missing symbols
Add "xvmc-nouveau/target.c" - missing symbol "driver_description"
Add "drivers/nvc0/libnvc0.a" - missing symbol "nvc0_screen_create"
Remove "drivers/softpipe/libsoftpipe.a" - unnessecary dependency
resolves build (when building without swrast)
Add "drivers/trace/libtrace.a" in Makefile
Note: With/without those patches xvmc-nouveau still segfaults

Use all zpass data for predication instead of the last block only.
Use query buffer as a ring instead of reusing the same area
for each new BeginQuery. All query buffer offsets are in bytes
to simplify offsets math.
The forward references to video enum types in p_context.h causes
a massive number of compiler warnings (ISO C forbids forward references
to ‘enum’ types).
By putting the new video enums in a separate header that can be included
by p_context.h and p_screen.h we can avoid this.
