Replace expose-event handler with draw handler in GTK3
In GTK3 the 'expose-event' signal has been replaced by a new 'draw' signal. The only difference is that the latter will pre-create the cairo drawing context & set the clip mask. Since the drawing code is already structured in a nice way, we can just wire up the 'gd_draw_event' method to the 'draw' signal in GTK3 Signed-off-by: Daniel P.
