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
and 1bbf803e3b from master which didn't
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.
NOTE: this will be applied to the 7.8 branch too.

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.
Fixes piglit tests fdo23670-depth_test, quad-invariance and
glsl-orangebook-ch06-bump as well as oglc zbfunc.c.

We would run into trouble due to the hardware using inclusive numbers
and the subtraction to handle that producing negative (meaning large
positive) coordinates.
Bug #27643.

We were doubling up the offsets for the mipmap levels for CPU access.
Instead of reimplementing i945_miptree_layout_2d with 6 cube images
separated by qpitch, share that function and provide the level offsets
later.
Fixes piglit cubemap and fbo-cubemap.
(cherry picked from commit 7d8f0fc282
Conflict due to mt->pitch still being here resolved -- i945 layout
should set it.)
Rename old IGDNG to Ironlake, and set 'gen' number for
Ironlake as 5, so tracking the features with generation num
instead of special is_ironlake flag.

This prevents memory usage explosion in blender due to the state cache
hanging on to old fake frontbuffer regions. Sigh at blender still
using frontbuffer rendering.
Bug #24119.
(cherry picked from commit ce914fff08)
Most of the failure from using uninlined function calls ends up being
just bad rendering, but nested function calls in the VS currently hang
the GPU, so reject them and explain why.

And lookup the GLX screen for the context. Otherwise we'll end up

The slang_variable::declared field originated as a debug field but

These files are built with make and removed with make clean, so it does not
seem necessary to track them.
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

In the lack of more fine grained capabilities in Gallium, assume that if

The removal of _glapi_noop_enable_warnings and _glapi_set_warning_func
in e4f168a6f4 prevents DRI drivers built
before the commit from loading. Add stub versions of the functions to
make them load again.
__glXInitializeVisualConfigFromTags doesn't skip the payload of
unrecognized tags. Instead, it treats the value as if it were the
next tag, which can happen if the server's GLX extension is not
Mesa's. For example, this falls down when NVIDIA sends a
GLX_FLOAT_COMPONENTS_NV = 0 pair, causing
__glXInitializeVisualConfigFromTags to bail out early.
