+Subject: [PATCH 2/6] Don't discriminate PAD and REFLECT repeat in standard fast paths
+
+Without this fix, setting PAD repeat on a source image prevents
+the use of any nonscaled standard fast paths, affecting performance
+a lot. But as long as no pixels outside the source image boundaries
+are touched by the compositing operation, all the repeat types
+behave the same and can take the same fast paths.
+
+This is important because setting PAD repeat instead of NONE is
+more hardware acceleration friendly (for the drivers implementing
+RENDER extension) and does not inhibit OVER->SRC operator
+optimization in pixman.

+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).
