* the best precision we want to make sure that we only clip once per
* side to avoid accumulating errors due to the scaling adjustment.
*
* For example, if src_x0 and dst_x0 need both to be clipped we want to
* avoid the situation where we clip src_x0 first, then adjust dst_x0
* accordingly but then we realize that the resulting dst_x0 still needs
* to be clipped, so we clip dst_x0 and adjust src_x0 again. Because we are
* applying scaling factors to adjust the coordinates in each clipping
* pass we lose some precision and that can affect the results of the
* blorp blit operation slightly. What we want to do here is detect the
* rect that we should clip first for each side so that when we adjust
* the other rect we ensure the resulting coordinate does not need to be
* clipped again.
*
* The code below implements this by comparing the number of pixels that
* we need to clip for each side of both rects considering the scales
* involved. For example, clip_src_x0 represents the number of pixels
* to be clipped for the src rect's left side, so if clip_src_x0 = 5,
* clip_dst_x0 = 4 and scale_x = 2 it means that we are clipping more
* from the dst rect so we should clip dst_x0 only and adjust src_x0.
* This is because clipping 4 pixels in the dst is equivalent to
* clipping 4 * 2 = 8 > 5 in the src.
