GraphEnter


tells Logo to enter a Graph. This is useful in a multithreading application, when a thread is known to have to draw a lot, to speed up the drawing. The number of calls to GraphEnter and GraphLeave should be the same until the program exits. Otherwise it may happen that a Graph is unresponsive when trying to draw.

For an example see testfiber.lg!
