Class Transition

java.lang.Object
org.openpatch.scratch.Transition
public final class Transition extends Object
How one stage gives way to the next in window.transitionToStage(…). A transition is a small shader that mixes the old stage's picture (from) and the new one's (to) by progress, from 0 to 1; the built-in ones cover the usual cases, and fromShader(String) makes one of your own: 
void main() {
  color = mix(texture(from, uv), texture(to, uv), progress);
}

During a transition the old stage stands still, the new stage's run() starts once the transition is over, and input is ignored.
