Chad Versace cc502aa941 intel: Fix intel_map_renderbuffer() for depthstencil buffers with separate stencil 
For a depthstencil buffer with separate stencil,
intel_renderbuffer::region is null. (The regions are kept in hidden depth
and stencil buffers). Since the region is null, intel_map_renderbuffer()
assumed there was no data and returned a null map pointer, which in turn
was dereferenced (!) by MapRenderbuffer's caller.

This patch fixes intel_map_renderbuffer() to map the hidden depth buffer
through the GTT and return that as the mapped pointer. Also, the stencil
bits are scattered and gathered when needed.

Fixes the following Piglit tests on gen7:
    fbo/fbo-readpixels-depth-formats
    hiz/hiz-depth-read-fbo-d24s8
    hiz/hiz-stencil-read-fbo-d24s8

docs/README.WIN32 

File: docs/README.WIN32

Last updated: 23 April 2011


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.


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.
