Reference: drawPixmap

drawPixmap(s, x, y) draws the pixmap named s (a string representing a valid identifier of a pixmap variable) at the point (x, y) in the current 2D visualization window. (x, y) is given in the visualization window's logical coordinates.

drawPixmap(s, x, y, fmt) draws the pixmap using the style (CSS) fmt.

Possible parameters for fmt:
   box-origin: top-left, top-center, top-right, middle-left, middle-center, middle-right, bottom-left, bottom-center, and bottom-right specifies what point on the pixmap is to be located above (x, y).

Example: drawPixmap("ball", 0, 0, "box-origin: middle-center") if "ball" is a previously defined pixmap.
