include/fixedmath.h: Regarding the single precision float to/from fixed point conversions in fixedmath.h, I believe the floating point literals should be appended with the letter 'f' to avoid (expensive) conversions from single to double precision, and thereby also avoid (expensive if done in SW) double point arithmetic (which is what is happening upon inspection of my disassembly).
