Bug: Original GDK event not set


I've just wanted to notify you about a small annoyance:
FigureCanvasGTK does not set the guiEvent attribute of the generated events to the original GDK event but leaves it to None. This is trivial to fix by just adding 'event' to the relevant calls to the event handlers of FigureCanvasBase.

Please fix it, my code depends on it :slight_smile:
