When building OSMesa and xlib GL, the resulting OSMesa would be linked
against libGL instead of the internal mesa libraries. However, when
building with -fvisibility=hidden, some of the internal functions used
in OSMesa could not be resolved through libGL.
Instead, always build OSMesa standalone without linking against libGL.
This has the advantage that OSMesa is always built the same way, but it
means that disk space is wasted when libGL is installed since both
libraries will contain the internal objects.

Otherwise, we'd run into minlod > maxlod, and the sampler would give

If you used all 4 color targets we currently support, we would see 0

can do the maximum of 16.
Fixes piglit fbo-drawbuffers-maxtargets.

The RGBX version isn't supported as a vertex input type, but since we
force the last channel's value anyway, this should be fine. The only
potential risk I see is in the limiter on VBO reads past the end of
the buffer forcing the whole vertex to 0 when the A channel lands past
the end.
Fixes piglit draw-vertices-half-float.

The support for XRGB8888 appeared in the 855 and 865, and this format
is reserved on 830/845. This should fix a regression from

on 845s.
Bug #26557.

The drawing rectangle is given in *inclusive* pixel values, so the range
is only [0,2047]. Hence when rendering to a 2048 wide target, such as an
extended desktop, we would issue an illegal instruction zeroing the draw
area.

This lets Mesa work like other OpenGL implementations with regard
to indexing uniform arrays. See comments for details.
This is a combination of commits 5d0e136eff

Based on commit 26a9b7e4c7 from master.
But fix the formatting and don't dereference the pointer to avoid a

We want to check the incoming renderbuffer format, not the (potentially
non-existant) current attachment.
Fixes segfault w/ fbotexture -ds2.

Convert Z from a normalized value in the range [0, 1] to an
object-space Z coordinate in [-1, +1] so that drawing at the new Z
position with the default/identity ortho projection results in the
original Z value. Used by the meta-Clear, Draw/CopyPixels and Bitmap
functions where the Z value comes from the clear value or raster
position.

We were doubling up the offsets for the mipmap levels for CPU access.
Instead of reimplementing i945_miptree_layout_2d with 6 cube images

later.

These files are built with make and removed with make clean, so it does not

Looking at the Makefile, it seems that the two u_indices_* files are handled
similarly to u_format_srgb.c u_format_table.c and u_half.c, and these 3
files are already untracked and in .gitignore
