When I build osmesa with --with-osmesa-bits=32 I notice that I get 31 bits by way of the compile line define -DDEFAULT_SOFTWARE_DEPTH_BITS=31. What's the story with the number 31? Is 31 bits really better than 32?
IIRC, 32 bit Z never worked properly because of float->int conversion problems and such. I think I found that 31 bits worked though. It's been a long time...
