Marek Olšák ca2c28859e r300g: implement MSAA compression and fast MSAA color clear
These are optimizations which make MSAA a lot faster.

The MSAA work is complete with this commit.  (except for enablement of AA
optimizations for RGBA16F, for which a patch is ready and waiting until
the kernel CS checker fix lands)

MSAA can't be made any faster as far as hw programming is concerned.

The catch is only one process and one colorbuffer can use the optimizations
at a time.  There usually is only one MSAA colorbuffer, so it shouldn't be
an issue.

Also, there is a limit on the size of MSAA colorbuffer resolution in terms
of megapixels.  If the limit is surpassed, the AA optimizations are disabled.
The limit is:
- 1 Mpix on low-end and some mid-level chipsets (1024x768 and 1280x720)
- 2 Mpix on some mid-level chipsets (1600x1200 and 1920x1080)
- 3 or 4 Mpix on high-end chipsets (2048x1536 or 2560x1600, respectively)
It corresponds to the number of raster pipes (= GB pipes) available, each pipe
can hold 1 Mpix of AA compression data.

If it's enabled, the driver prints to stdout:
  radeon: Acquired access to AA optimizations.

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.
