Paul Berry 532b1fecd9 i965: Fix clears of layered framebuffers with mismatched layer counts.
Previously, Mesa enforced the following rule (from
ARB_geometry_shader4's list of criteria for framebuffer completeness):

  * If any framebuffer attachment is layered, all attachments must have
    the same layer count.  For three-dimensional textures, the layer count
    is the depth of the attached volume.  For cube map textures, the layer
    count is always six.  For one- and two-dimensional array textures, the
    layer count is simply the number of layers in the array texture.
    { FRAMEBUFFER_INCOMPLETE_LAYER_COUNT_ARB }

However, when ARB_geometry_shader4 was adopted into GL 3.2, this rule
was dropped; GL 3.2 permits different attachments to have different
layer counts.  This patch brings Mesa in line with GL 3.2.

In order to ensure that layered clears properly clear all layers, we
now have to keep track of the maximum number of layers in a layered
framebuffer.

Fixes the following piglit tests in spec/!OpenGL 3.2/layered-rendering:
- clear-color-all-types 1d_array mipmapped
- clear-color-all-types 1d_array single_level
- clear-color-mismatched-layer-count
- framebuffer-layer-count-mismatch

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 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.
