struct fraction is slooooooooooow. This patch adds a simple 64-bit (32-bits integral, 32-bits fractional) fixed-point math API that is *much* faster (observed roughly 5x speed-up) when doing intensive graphics operations. It is optimized for speed over accuracy so some operations may lose a bit more precision than expected, but overall it's still plenty of bits for most use cases. Also includes support for basic trigonometric functions with a small lookup table.
