4Subject: [PATCH 2/2] Generic C implementation of pixman_blt with overlapping
5 support
6MIME-Version: 1.0
7Content-Type: text/plain; charset=UTF-8
8Content-Transfer-Encoding: 8bit
9
10This was ported from meta-oe's patch [1]:
11Uses memcpy/memmove functions to copy pixels, can handle the
12case when both source and destination areas are in the same
13image (this is useful for scrolling).
14
15It is assumed that copying direction is only important when
16using the same image for both source and destination (and
17src_stride == dst_stride). Copying direction is undefined
18for the images with different source and destination stride
19which happen to be in the overlapped areas (but this is an
20unrealistic case anyway).
