Hi all!
Right now, states should draw the transitions that they need ( fade in / fade out / pixelate / whatever). So the state manager calls

CurrentState->drawTransition(TRANSITION_OUT, time);
NextState->drawTransition(TRANSITION_IN, time);

drawTransition is a pure virtual function which each state should implement.

What's the actual, neat, non hacky method to do this?

Thanks
