    _______________________________________________________

Details:

If a user creates a GUI with uicontrol etc., then callbacks that modify a
graph do not cause the graph to be redrawn.  They set Vdrawnow_requested, but
nothing checks if that is set (until a command prompt or such).

Matlab draws the object immediately.

I'll attach the (trivial) patch to fix this once I have the bug number.
