10 | This was ported from meta-oe's patch [1]: | ||
11 | Uses memcpy/memmove functions to copy pixels, can handle the | ||
12 | case when both source and destination areas are in the same | ||
13 | image (this is useful for scrolling). | ||
14 | |||
15 | It is assumed that copying direction is only important when | ||
16 | using the same image for both source and destination (and | ||
17 | src_stride == dst_stride). Copying direction is undefined | ||
18 | for the images with different source and destination stride | ||
19 | which happen to be in the overlapped areas (but this is an | ||
20 | unrealistic case anyway). | ||
