    i965: fix bugs in projective texture coordinates
    
    For the TXP instruction we check if the texcoord is really a 4-component
    atttibute which requires the divide by W step.  This check involved the
    projtex_mask field.  However, the projtex_mask field was being miscalculated
    because of some confusion between vertex program outputs and fragment
    program inputs.
    
    1. Rework the size_masks calculation so we correctly set bits corresponding
    to fragment program input attributes.
    
    2. Rename projtex_mask to proj_attrib_mask since we're interested in more
    than just texcoords (generic varying vars too).
    
    3. Simply the indexing of the size_masks and proj_attrib_mask fields.
    
    4. The tracker::active[] array was mis-dimensioned.  Use MAX_PROGRAM_TEMPS
    instead of a magic number.
    
    5. Update comments, add new assertions.
    
    With these changes the Lightsmark demo/benchmark renders correctly, until
    we eventually hit a GPU lockup...

    softpipe: fix out of bounds quad rasterization bug
    
    For some triangles we can generate quads which lie just outside the
    surface bounds.  Just check the quad's mask before trying to emit/process
    the quad.
    
    Fixes failed assertion in Lightsmark.

    mesa: fix incorrect viewport clamping in _mesa_set_viewport()
    
    A 0 by 0 viewport size is legal.  Don't clamp against lower bound of one.
    The error checking earlier in the function prevents negative values.

    softpipe: Fix softpipe_is_texture_referenced.
    
    Render results are only visible when the render cache is flushed.
    softpipe_is_texture_referenced must reflect that or transfers to/from the
    textures bound in the framebuffer won't be proceeded of the necessary
    flush, causing transfer data to be outdated/clobbered.
    
    This fixes conform drawpix test with softpipe.

    progs/tests: Use opaque colors.
    
    Transparency is not relevant for this example, and leads to distraction
    due to different results in alpha visuals, when capturing images to disk.
