Nicolai Hähnle 322483f71b st/mesa: fix the layer of VDPAU surface samplers 
A (latent) bug in VDPAU interop was exposed by commit
e5cc84dd43.

Before that commit, the st_vdpau code created samplers with
first_layer == last_layer == 1 that the general texture handling code
would immediately delete and re-create, because the layer does not match
the information in the GL texture object.

This was correct behavior at least in the DMABUF case, because the imported
resource is supposed to have the correct offset already applied.  In the
non-DMABUF case, this was just plain wrong but apparently nobody noticed.

After that commit, the state tracker assumes that an existing sampler is
correct at all times.  Existing samplers are supposed to be deleted when
they may become invalid, and they will be created on-demand.  This meant
that the sampler with first_layer == last_layer == 1 stuck around, leading
to rendering artefacts (on radeonsi), command stream failures (on r600), and
assertions (in debug builds everywhere).

This patch fixes the problem by simply not creating a sampler at all in
st_vdpau_map_surface.  We rely on the generic texture code to do the right
thing, adding the layer_override to make the non-DMABUF case work.

v2: add the layer_override

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.
