Read as an integer, a float's bits are its log2 with the mantissa a
straight line between powers of two, scaled by 2^23, and writing an
integer back is the matching exp2. That's exactly the GE's
approximation, without log2/exp2/floor. pspPow now also returns 1 for
e <= 0 itself, so the callers drop their checks. Shader languages
without integers fall back to a true pow.
