    st/mesa: rework viewport/scissor initialization code
    
    This is a hand-pick of some of the new viewport code committed to
    mesa_7_5_branch.
    See commit 3f856c6b6b7fa95ef97a8712876de88d7d57932e for reference.
    
    This is just the state_tracker part.  The core Mesa part came from
    merging in mesa_7_4_branch.

    mesa: rework viewport/scissor initialization code
    
    The first time a context is bound to a drawable, the viewport and scissor
    bounds are initialized to the buffer's size.  This is actually a bit tricky.
    
    A new _mesa_check_init_viewport() function is called in several places
    to check if the viewport has been initialized.  We also use a new
    ctx->ViewportInitialized flag instead of the overloaded
    ctx->FirstTimeCurrent flag.

    GLX: attempt to fix glean makeCurrent test cases.
    
    Two parts to this:
    
    One we don't keep pointers to possibly freed memory anymore once we unbind the
    drawables from the context. Brian I need to figure out what the comment
    you made there, can we get a glean/piglit test so we can fix it properly?
    
    If the new gc is the same as the oldGC, we call the unbind even though
    we just bound it in that function. doh.

    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.

    osmesa: Allow building standalone in all three channel widths
    
    autoconf had been designating the 8 bit libOSMesa as the default
    standalone osmesa, but the Makefile expected it to be linked to libGL.
    Fix up the osmesa Makefile so that it allows any of the combinations of
    standalone and channel width to be built.
    
    Fixes bug #21980.

    demos: fix multitex.c VertCoord attribute mapping
    
    If the multitex.vert shader uses the VertCoord generic vertex attribute
    instead of the pre-defined gl_Vertex attribute, we need to make sure that
    VertCoord gets bound to generic vertex attribute zero.
    
    That's because we need to call glVertexAttrib2fv(0, xy) after all the other
    vertex attributes have been set since setting generic attribute 0 triggers
    vertex submission.  Before, we wound up issuing the vertex attributes in
    the order 0, 1, 2 which caused the first vertex to be submitted before all
    the attributes were set.  Now, the attributes are set in 1, 2, 0 order.

    vbo: fix crash in vbo_exec_bind_arrays()
    
    When a vertex shader uses generic vertex attribute 0, but not gl_Vertex,
    we need to set attribute[16] to point to attribute[0].  We were setting the
    attribute size, but not the pointer.
    
    Fixes crash in glsl/multitex.c when using the VertCoord attribute instead
    of gl_Vertex.

    The generic_array[] is 16 elements in size, but the loop was doing 32
    iterations.  The out of bounds array write was clobbering the following
    inputs[] array but as luck would have it, that didn't matter.

    i965: fix render to FBO/texture orientation bugs
    
    Anytime we're not rendering to the default/window FBO, need to invert
    rendering, not just when rendering to a texture.  Otherwise, if a FBO
    consists of a mix of textures and renderbuffers the up/down orientation
    was inconsistant.
    
    Fixes shadowtex.c bad rendering.

    mesa: Fixed a texture memory leak
    
    The current texture for any particular texture unit is given an additional
    reference in update_texture_state(); but if the context is closed before
    that texture can be released (which is quite frequent in normal use, unless
    a program unbinds and deletes the texture and renders without it to force
    a call to update_texture_state(), the memory is lost.
    
    This affects general Mesa; but the i965 is particularly affected because
    it allocates a considerable amount of additional memory for each allocated
    texture.
