we need to move the "continous/non-continous" code snippet out of ConcreteSimulation
and into TextualSimulation/the GUI Simulation. In fact, ConcreteSimulation
is just a state machine that performs a single step and then puts itself
either in paused state (if the Simulation hasn't finished) or into stopped state
(if it finished)

The problem didn't show in versions of cairo >= 1.2 because it automagically
clips (yeah, cairo programmers *are* smart :-))

mutexes and set the value when needed (maybe we can improve this?)
