/*
* FUNCTIONS
* mlib_ImageConvCopyEdge - Copy src edges to dst edges
*
*
* SYNOPSIS
* mlib_status mlib_ImageConvCopyEdge(mlib_image *dst,
* const mlib_image *src,
* mlib_s32 dx_l,
* mlib_s32 dx_r,
* mlib_s32 dy_t,
* mlib_s32 dy_b,
* mlib_s32 cmask)
*
* ARGUMENT
* dst Pointer to an dst image.
* src Pointer to an src image.
* dx_l Number of columns on the left side of the
* image to be copyed.
* dx_r Number of columns on the right side of the
* image to be copyed.
* dy_t Number of rows on the top edge of the
* image to be copyed.
* dy_b Number of rows on the top edge of the
* image to be copyed.
* cmask Channel mask to indicate the channels to be convolved.
* Each bit of which represents a channel in the image. The
* channels corresponded to 1 bits are those to be processed.
*
* RESTRICTION
* The src and the dst must be the same type, same width, same height and have same number
* of channels (1, 2, 3, or 4). The unselected channels are not
* overwritten. If both src and dst have just one channel,
* cmask is ignored.
*
* DESCRIPTION
* Copy src edges to dst edges.
* The unselected channels are not overwritten.
* If src and dst have just one channel,
* cmask is ignored.
