Steve Checkoway 1b96c0da14 Use fixed point math for the inner loop of ZoomSurface(). This gives a huge speedup on PowerPC. ...

Note that 16777216=2^24 is 1.0 in U(8,24) fixed point and 8388608=2^23 is 0.5. Also, single precision IEEE floating point has 23 bits of mantissa and U(8,24) has 24 bits of fraction so no precision is lost.
