// Animation:
//

// However you can override this behaviour with custom show/hide animation routines,
// as we have done in the "Menu Effects" section. Feel free to edit this, or delete
// this entire function if you're not using it. Basically, make functions to handle
// menuObj.showAnim() and .hideAnim(), both of which are passed menu names.
//
// Customisers: My lyr.clip() command gets passed the parameters (x1, y1, x2, y2)
// so you might want to adjust the direction etc. Oh, and I'm adding 2 to the dimensions
// to be safe due to different box models in some browsers.
// Another idea: add some if/thens to test for specific menu names...?

  //lyr.clip(0, (menuH+2)-(menuH+2)*Math.pow(Math.sin(Math.PI*counter/200),0.75), menuW+2, menuH+2);
  // Another alternative: Move+clip sliding animation. Looks really cool :).
  //if (!counter) mD.origY = lyr.y();
