/*
* FUNCTION
* mlib_convMxN_8nw - convolve a 8-bit image, MxN kernel,
* edge = no write
*
* SYNOPSIS
* mlib_status mlib_convMxNnw_u8(mlib_image *dst,
* const mlib_image *src,
* mlib_s32 kwid,
* mlib_s32 khgt,
* mlib_s32 khw,
* mlib_s32 khh,
* const mlib_s32 *skernel,
* mlib_s32 discardbits,
* mlib_s32 cmask)
*
* ARGUMENT
* src Ptr to source image structure
* dst Ptr to destination image structure
* khgt Kernel height (# of rows)
* kwid Kernel width (# of cols)
* skernel Ptr to convolution kernel
* discardbits The number of LSBits of the 32-bit accumulator that
* are discarded when the 32-bit accumulator is converted
* to 16-bit output data; discardbits must be 1-15 (it
* cannot be zero). Same as exponent N for scalefac=2**N.
* 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.
*
* DESCRIPTION
* A 2-D convolution (MxN kernel) for 8-bit images.
