Kenneth Graunke 8c1c18769e i965/blorp: Add support for blits between SRGB and linear formats (fixed). 
This is a squash of 2 commits from master.
The first commit is:

i965/blorp: Add support for blits between SRGB and linear formats.

Fixes colorspace issues in L4D2 when multisampling is enabled (the
scene was far too dark, but the flashlight area was way too bright).

The nVidia and AMD binary drivers both allow this kind of blit.

The second commit is:

i965/blorp: Fix sRGB MSAA resolves.

Commit e2249e8c4d (i965/blorp: Add
support for blits between SRGB and linear formats) changed blorp to
always configure surface states for in linear format (even if the
underlying surface is sRGB).  This allowed sRGB-to-linear and
linear-to-sRGB blits to occur without causing the image to be
inappropriately brightened or darkened.

However, it broke sRGB MSAA resolves, since they rely on the
destination buffer format being sRGB in order to ensure that samples
are averaged together in sRGB-correct fashion.

This patch fixes the problem by instead configuring the source buffer
to use the *same* format as the destination buffer.  This ensures that
the image won't be brightened or darkened, but preserves proper sRGB
averaging.

Fixes piglit tests "EXT_framebuffer_multisample/accuracy srgb".

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.
