    i965: asst. fixes, work-arounds for FBOs and render to texture
    
    OpenGL allows mixing and matching depth and stencil renderbuffers in
    framebuffer objects while the hardware really only supports interleaved
    depth/stencil buffers.  This makes for some tricky buffer management.
    
    An extra wrinkle is the situation where the user allocates a 16bpp depth
    texture or renderbuffer then tries to render to it along with a stencil
    buffer.  We'd have to promote the 16bpp Z values to 24-bit Z values and
    mix in the stencil values to setup the depth/stencil renderbuffer.
    
    There's no support for that now, so always allocate 32bpp depth textures/
    renderbuffers for now.

    mesa: fix incorrect transformation of GL_SPOT_DIRECTION
    
    This was changed between GL 1.0 and 1.1.  Mesa still had the 1.0 behaviour.

commit 2549c26a8b1eec21bdd8f45d3b3dd06e17ac82ae
Author: Ian Romanick <ian.d.romanick@intel.com>
Date:   Wed Jan 14 10:05:40 2009 -0800

    Treat image units and coordinate units differently.
    
    Previously MaxTextureUnits was used to validate both texture image
    units and texture coordinate units in fragment programs.  Instead, use
    MaxTextureCoordUnits for texture coordinate units and
    MaxTextureImageUnits for texture image units.
    
    Fixes bugzilla #19468.
