Anuj Phogat ad4b3b93de _mesa_meta_GenerateMipmap: Support all texture targets by generating shaders at runtime
This is a squash for the following 7 commits.  The first introduces the
functionality, and the remaining six fix various bugs.

Patch 1:
    _mesa_meta_GenerateMipmap: Support all texture targets by generating shaders at runtime

    glsl path of _mesa_meta_GenerateMipmap() function would require different fragment
    shaders depending on the texture target. This patch adds the code to generate
    appropriate fragment shader programs at run time.
    Fixes https://bugs.freedesktop.org/show_bug.cgi?id=54296

    V2: Removed the code for integer textures as ARB is planning to
        disallow automatic mipmap generation for integer textures.
        Now using ralloc_asprintf in setup_glsl_generate_mipmap().

    NOTE: This is a candidate for stable branches.

    (cherry picked from commit 299acac849)

Patch 2:
    _mesa_meta_GenerateMipmap: Generate separate shaders for glsl 120 / 130

    glsl version of _mesa_meta_GenerateMipmap() would require separate
    shaders for glsl 120 and 130.

    V2: Removed the code for integer textures as ARB is planning to
        disallow automatic mipmap generation for integer textures.

Patch 3:
    meta: Add on demand compilation of per target shader programs

    A call to glGenerateMipmap() follows the generation of a relevant
    shader program in setup_glsl_generate_mipmap().

    To support all texture targets and to avoid compiling shaders
    everytime, per target shader programs are compiled on demand
    and saved for the next call.

    Fixes float-texture(mipmap.manual):

Patch 4:
    meta: make mem_ctx non-global.

    I can't see any external users, and this is a global symbol,

Patch 6:
    meta: Rearrange shader creation in setup_glsl_generate_mipmap

    The diff looks weird, but this moves the code from the first 'if
    (ctx->Const.GLSLVersion < 130)' block down into the second block.  It
    also moves some variable decalarations closer to their use.

    NOTE: This is a candidate for the 9.0 branch.

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.
