I've added a PosImage object to Wumpus-Basic. This is a rectangular object that can be drawn at any of its corners (other rectangles in Wumpus can only be drawn from their center or baseline left).
The idea for PosImage is to use it as a container for at least LRText. LRText should be readily positionable, but currently it isn't as the number of functions exported by API would have exploded. PosImage avoids this by encoding all positions in an Enum.
