Aliases

fix alias fix = SignedBitsType!(COLOR.channelBits + coordinateBits): Fixed-point type, big enough to hold a coordinate, with fractionary precision corresponding to channel precision.
fix2 alias fix2 = SignedBitsType!(COLOR.channelBits * 2 + coordinateBits): Type to hold temporary values for multiplication and division
frac alias frac = COLOR.ChannelType: Type only large enough to hold a fractionary part of a "fix" (i.e. color channel precision). Used for alpha values, etc.
frac2 alias frac2 = UnsignedBitsType!(COLOR.channelBits * 2): Type to hold temporary values for multiplication and division
