commit a663e846b63c33685a9e88c8904f5e3a225f6e85
Author: Ian Romanick <idr at us.ibm.com>
Date:   Wed Oct 17 13:11:01 2007 -0700

    Framework for supporting z24_s8 and z32 depth textures on r300.

commit 42a4386a4c18932221c59607e6d22b864a2577fb
Author: Ian Romanick <idr at us.ibm.com>
Date:   Wed Oct 17 12:07:04 2007 -0700

    Initial support for ARB_depth_texture
    
    Currently only GL_DEPTH_COMPONENT16 are supported.  I don't know what the
    hardware bits are to select the other formats, but it shouldn't be too hard
    to figure out.
