There is one part I need to change...but I cannot figure out where it is in the code. The current patch limits the canvas display to horizontal or vertical, but the actual painting still always wraps both vertical and horizontal. Where is the painting calculation for that being done?
Even with its current limitation, this is still a pretty helpful patch I think.
