Jordan Justen bf25ee2840 gen7 depth surface: program 3DSTATE_DEPTH_BUFFER to top of surface
Previously we would always find the 2D sub-surface of interest,
and then program the surface to this location. Now we always
program the 3DSTATE_DEPTH_BUFFER at the start of the surface.
To select the lod/slice, we utilize the lod & minimum array
element fields.

As part of this change, we must revert 1f112ccf:
Revert "i965/gen7: Align all depth miplevels to 8 in the X direction."

We also must disable brw_workaround_depthstencil_alignment for
gen >= 7. Now the hardware will handle alignment when rendering
to additional slices/LODs.

v2:
 * Merge with recent MOCS changes

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

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

Run

  scons osmesa mesagdi

to build classic mesa Windows GDI drivers; or

  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.

1) install python 2.7
2) install scons (latest)
3) install mingw, flex, and bison
4) install libxml2 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get libxml2-python-2.9.1.win-amd64-py2.7.exe
5) install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
6) install git
7) download mesa from git
  see http://www.mesa3d.org/repository.html
8) 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.
