- Added texture support (not yet working; also texblits not implementedati-5-0-0-20001223-freeze

    yet)
- Added workaround for overwriting VB problem (does not completely solve
    the problem -- Q3A, gloss among others will still demonstrate the
    problem)
- Added window offsets support
- Fixed depth offset initialization
- Changed visuals to support 24bpp instead of 32bpp depth buffers to match
    Mesa's depth buffer support
