Kenneth Graunke 60d6a8989a i965: Set address rounding bits for GL_NEAREST filtering as well. 
Yuanhan Liu decided these were useful for linear filtering in
commit 76669381 (circa 2011).  Prior to that, we never set them;
it seems he tried to preserve that behavior for nearest filtering.

It turns out they're useful for nearest filtering, too: setting
these fixes the following dEQP-GLES3 tests:

functional.fbo.blit.rect.nearest_consistency_mag
functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_x
functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_y
functional.fbo.blit.rect.nearest_consistency_mag_reverse_dst_x
functional.fbo.blit.rect.nearest_consistency_mag_reverse_dst_y
functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_dst_x
functional.fbo.blit.rect.nearest_consistency_mag_reverse_src_dst_y
functional.fbo.blit.rect.nearest_consistency_min
functional.fbo.blit.rect.nearest_consistency_min_reverse_src_x
functional.fbo.blit.rect.nearest_consistency_min_reverse_src_y
functional.fbo.blit.rect.nearest_consistency_min_reverse_dst_x
functional.fbo.blit.rect.nearest_consistency_min_reverse_dst_y
functional.fbo.blit.rect.nearest_consistency_min_reverse_src_dst_x
functional.fbo.blit.rect.nearest_consistency_min_reverse_src_dst_y
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag_reverse_src_x
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag_reverse_src_y
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag_reverse_dst_x
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag_reverse_dst_y
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag_reverse_src_dst_x
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_mag_reverse_src_dst_y
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min_reverse_src_x
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min_reverse_src_y
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min_reverse_dst_x
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min_reverse_dst_y
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min_reverse_src_dst_x
functional.fbo.blit.rect.nearest_consistency_out_of_bounds_min_reverse_src_dst_y

Apparently, BLORP has always set these bits unconditionally.

However, setting them unconditionally appears to regress tests using
texture projection, 3D samplers, integer formats, and vertex shaders,
all in combination, such as:

functional.shaders.texture_functions.textureprojlod.isampler3d_vertex

Setting them on Gen4-5 appears to regress Piglit's
tests/spec/arb_sampler_objects/framebufferblit.

Honestly, it looks like the real problem here is a lack of precision.
I'm just hacking around problems here (as embarassing as it is).

docs/README.WIN32 

File: docs/README.WIN32

Last updated: 21 June 2013


Quick Start
----- -----

Windows drivers are build with SCons.  Makefiles or Visual Studio projects are
no longer shipped or supported.

Run

  scons libgl-gdi

to build gallium based GDI driver.

This will work both with MSVS or Mingw.


Windows Drivers
------- -------

At this time, only the gallium GDI driver is known to work.

Source code also exists in the tree for other drivers in
src/mesa/drivers/windows, but the status of this code is unknown.

Recipe
------

Building on windows requires several open-source packages. These are
steps that work as of this writing.

- install python 2.7
- install scons (latest)
- install mingw, flex, and bison
- install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
- install git
- download mesa from git
  see http://www.mesa3d.org/repository.html
- run scons

General
-------

After building, you can copy the above DLL files to a place in your
PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
in a system directory, place them in the same directory as the
executable(s).  Be careful about accidentially overwriting files of
the same name in the SYSTEM32 directory.

The DLL files are built so that the external entry points use the
stdcall calling convention.

Static LIB files are not built.  The LIB files that are built with are
the linker import files associated with the DLL files.

The si-glu sources are used to build the GLU libs.  This was done
mainly to get the better tessellator code.

If you have a Windows-related build problem or question, please post
to the mesa-dev or mesa-users list.
