+ * Main encoding function
+ * Returns the grid (malloced) containing the matrix. L corner at 0,0.
+ * Takes suggested size in *Wptr, *Hptr, or 0,0. Fills in actual size.
+ * Takes barcodelen and barcode to be encoded
+ * Note, if *encodingptr is null, then fills with auto picked (malloced) 
+ * encoding.
+ * If lenp not null, then the length of encoded data before any final unlatch 
+ * or pad is stored.
+ * If maxp not null, then the max storage of this size code is stored
+ * If eccp not null, then the number of ecc bytes used in this size is stored
+ * Returns 0 on error (writes to stderr with details).
