* SYNOPSIS
*
* ARGUMENT
* src pointer to source image data
* dst pointer to destination image data
* slb source image line stride in bytes
* dlb destination image line stride in bytes
* dsize image data size in pixels
* xsize image width in pixels
* ysize image height in lines
* cmask channel mask
*
* DESCRIPTION
* extract the right or left 3 channels of a 4-channel image to
* a 3-channel image -- VIS version low level functions.
*
* ABGR => BGR (43R), or RGBA => RGB (43L)
*
* NOTE
* These functions are separated from mlib_v_ImageChannelExtract.c
* for loop unrolling and structure clarity.
