| 1 | Generic C implementation of pixman_blt with overlapping support | ||
| 2 | |||
| 3 | This was ported from meta-oe's patch [1]: | ||
| 4 | Uses memcpy/memmove functions to copy pixels, can handle the | ||
| 5 | case when both source and destination areas are in the same | ||
| 6 | image (this is useful for scrolling). | ||
| 7 | |||
| 8 | It is assumed that copying direction is only important when | ||
| 9 | using the same image for both source and destination (and | ||
| 10 | src_stride == dst_stride). Copying direction is undefined | ||
| 11 | for the images with different source and destination stride | ||
| 12 | which happen to be in the overlapped areas (but this is an | ||
| 13 | unrealistic case anyway). | ||
