//  [opacity, 'layer colour', X offset, Y offset, Width Difference, Height difference]
// Opacity is from 0 to 100 (or null to make it solid), and the X/Y offsets are the
// distance in pixels from the menu's top left corner to that shadow layer's corner.
// The width/height differences are added or subtracted to the current menu size, for
// instance the first layer of this shadow is 4px narrower and shorter than the menu
// it is shadowing.

// If you don't want animation, delete this entirely, and the menus will act normally.
// Change the speed if you want... it's the last number, between -100 and 100, and is
// defined as the percentage the animation moves each frame (defaults are 10 and 15).

// Animation:
//
// Each menu object you create by default shows and hides its menus instantaneously.
// 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...?

  // and either the top or bottom is a complicated formula based on the 'counter' variable which
  // counts from 0 to 100 and back again; this give a nice accelerating-sliding animation.
  // Feel free to experiment with your own animations, here are some samples (use one only):

  // Straightforward downwards clipping animation (default setting):
  lyr.clip(0, 0, menuW+2, (menuH+2)*Math.pow(Math.sin(Math.PI*counter/200),0.75) );
  // If you want, comment out the above line and enable this one to animate bottom-upwards:
  //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();
  //var newY = (menuH+2)-(menuH+2)*Math.pow(Math.sin(Math.PI*counter/200),0.75);
  //lyr.clip(0, newY, menuW+2, menuH+2);
  //lyr.y(mD.origY - newY);

  // Increment the counter and if it hasn't reached the end (counter is 0% or 100%),
  // set the timer to call the animation function again in 40ms to contine the animation.
  // Note that we hide the menu div on animation end in that direction.
