+ * 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
