+delegation. This reduces call overhead somewhat. The saving
+is minor, but every little bit helps.

+Subject: [PATCH 3/6] Generic C implementation of pixman_blt with overlapping support
+
+Uses memcpy/memmove functions to copy pixels, can handle the
+case when both source and destination areas are in the same
+image (this is useful for scrolling).
+
+It is assumed that copying direction is only important when
+using the same image for both source and destination (and
+src_stride == dst_stride). Copying direction is undefined
+for the images with different source and destination stride
+which happen to be in the overlapped areas (but this is an
+unrealistic case anyway).
