MReMapShapeUsingShape RemapTable.l[,SourceShapeNum.w[,DestShapeNum.w]] ;Merge shape to shape using 2xWay Table

Does the same as MReMapUsingShape, except that a chunky Shape will be used
as the output rather than a chunky Bitmap. If DestShapeNum.w is not specified,
the /second/ currently used Shape will be assumed. The first used chunky Shape
will be assumed if SourceShapeNum is also omitted.
