converts a double to a rational that has less than one float bit of error (returns 0 if unable to do so)

this is how many coefficents per run of the filter (which is different from the filter_pixel_width depending on if we are scattering or gathering)

get information on the extents of a sampler

This is the maximum number of input samples that can affect an output sample with the given filter from the output pixel's perspective

memcpy that is specifically intentionally overlapping (src is smaller then dest, so can be a normal forward copy, bytes is divisible by 4 and bytes is
