former used fistp, which is not portable across platforms, so cannot be used in the play simulation. They were only suitable for the renderer. xs_Float.h also has a very fast float->fixed conversion, so FLOAT2FIXED uses that now. (And I also learned that the FPU's round to nearest is not the rounding I learned in grade school but actually Banker's Rounding. I had no idea.) (Also, also, the only thing that could have made quickertoint faster than toint was that it stored a 32-bit int. I never timed them, and I doubt in practice there was any real difference between the two.) - Changed atan2f to atan2. Using floats is not a win, because the result is returned as a double on the x87 stack, which the caller then needs to cast down to a float using fst/fld. SVN r1990 (trunk)
