-I/O

   Given: 
   src_mask        source mask
   size_factor     factor by which to scale up source mask
   
   the call:
   
      status = MTK_UPSAMPLE_MASK( src_mask, size_factor, resamp_mask )

   returns: 
    status         0 on success; otherwise failure
    resamp_mask    upscaled mask
   
   
-Examples
	;;
	;; Set up input parameters
	;;
	src_mask = byte(replicate(1,528,384))
	size_factor = 2
	;;
	;; The call
	;;
	status = MTK_UPSAMPLE_MASK( src_mask, size_factor, resamp_mask )
	;;
	;; Output...
	;;
	print, '================================================='
	help, src_mask, resamp_mask
	

	IDL outputs:
	=================================================
	SRC_MASK        BYTE      = Array[528, 384]
