* We try to detect the value from GL with test draws. On most drivers (r300g,
* 600g, Nvidia, i965 on Mesa) the value is 2^23 for fixed point depth buffers,
* for r200 and i965 on OSX it is 2^24, for r500 on OSX it is 2^22. For floating
* point buffers it is 2^22, 2^23 or 2^24 depending on the GPU. The value does
* not depend on the depth buffer precision on any driver.
*
* Two games that are picky regarding depth bias are Mass Effect 2 (flickering
* decals) and F.E.A.R and F.E.A.R. 2 (semi-transparent guns).
