commit 84d1b24647c0719551e8bcd5fa4601fbd3b1d555

    Fix ARB_fp spec conformance bug WRT shadow sampling.
    
    The ARB_fp (and other assembly-level fragment program specs) say that the
    depth comparison function is always GL_NONE in fragment program mode.

    Add support for shadow mapping with vertex and fragment programs

commit 2260c245fd5798a6b3661c3a529654d9f577821d

    Refactor shadow map modelview and projection code
    
    Explicitly store the modelview matrix and projection matrix used when the
    shadow map is created.  These matrices only need be updated when
    RenderShadowMap is called.  Previously, slightly different code was used to
    draw and project the shadow map.
