doc additions: shader export ARRAY_BASE for EXPORT_POS: 60 is position,
61 is misc vec(VS_OUT_MISC_VEC - used here),
62, 63 are clip distance vectors(VS_OUT_CCDIST#)
sorry for formating - there seem to be so many different styles in r600

there's no more vp results for point coords so we cannot iterate

This avoids calling radeonFlush() during context destruction, when
ctx->DrawBuffer would be NULL.
NOTE: This is a candidate for the 7.8 branch.

Fixes piglit object_purgeable-api-pbo, object_purgeable-api-vbo
and object_purgeable-api-texture failures with swrast.
NOTE: This is a candidate for the 7.8 branch.

When searching for valid miptree check images in range
of [BaseLeve, MaxLevel] not [MinLod, MaxLoad].
Prevents unnecessary miptree allocations in cases when during
every rendering operation different texture image level
was selected using MIN_LOD = MAX_LOD = level (for every level
new miptree for whole texture was allocated).
Candidate for 7.8 branch.

...instead of waiting until glGetString(GL_EXTENSIONS) is called.
This fixes a problem where the MESA_EXTENSION_OVERRIDE env var is
ignored if the app never calls glGetString(GL_EXTENSIONS).

There is no libdl on FreeBSD. Based on patch from Thinker

The following instruction sequence will no longer be emitted in separate
TEX blocks:
0: TEX temp[0].xyz, temp[1].xy__, 2D[0];
1: TEX temp[1].xyz, temp[2].xy__, 2D[0];
This fixes fdo bug #25109

st/egl uses GLX code for DRI2 support. It should honor
GLX_DIRECT_RENDERING.
Also updates configure.ac to define GLX_DIRECT_RENDERING for st/egl.

We check for libX11 and libXt, so we might as well use the CFLAGS

Fix this build error (in MesaGLUT-7.6.1)...
glut_cmap.c:23:66: error: X11/Xmu/StdCmap.h: No such file or directory
...by not preventing the cflags that pkg-config finds for glut dependencies
(including 'xmu') from being used.
Defining GLUT_CFLAGS before running the pkg-config prevents the
cflags found by pkg-config from being used.
This patch lets GLUT_CFLAGS that configure & pkg-config work
so hard to set actually get used.
Also make sure the generated configs/autoconf defines GLUT_CFLAGS
used in (at least) src/glut/glx/Makefile.

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.

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

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.
(cherry picked from commit f0ff214bee)
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.

apply cleanly with git cherry-pick.
update for fbconfig_style_tags
Based on commit 26a9b7e4c7 from master.
But fix the formatting and don't dereference the pointer to avoid a
compiler warning.
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.
