Returns the coordinate origin of a pixmap graphics port.
A graphics port.
This returns two values being the coordinate origin of the pixmap graphics port. Normally this is (0 0) but after a series of drawing function calls with
, the drawing may have been shifted. The
values tell you by how much. The values are
needed when making images from the port's drawing.
