Copy a rectangular area of samples to a temporary buffer and replicate the border samples.
| dst | destination buffer |
| dst_stride | number of bytes between 2 vertically adjacent samples in destination buffer |
| src | source buffer |
| dst_linesize | number of bytes between 2 vertically adjacent samples in the destination buffer |
| src_linesize | number of bytes between 2 vertically adjacent samples in both the source buffer |
| block_w | width of block |
| block_h | height of block |
| src_x | x coordinate of the top left sample of the block in the source buffer |
| src_y | y coordinate of the top left sample of the block in the source buffer |
| w | width of the source buffer |
| h | height of the source buffer |

Prefetch memory into cache (if supported by hardware).
| buf | pointer to buffer to prefetch memory from |
| stride | distance between two lines of buf (in bytes) |
| h | number of lines to prefetch |
