variable <- Get_Window_Height
Get_Window_Height is a function that returns the height, in pixels, of the currently opened RaptorGraph window. This can be useful, because the size of the opened RaptorGraph window is not always the size requested. This inconsistency most often occurs when especially small window sizes are requested via Open_Graph_Window.
A RaptorGraph window MUST be open when you call Get_Window_Height or a run-time error will occur.
