//  These properties enable repositioning of a UIView
//  by changing any single coordinate or size parameter.
//  Don't forget that you can also use UIView's autoresizing
//  mask to achieve some automatic layout.
//
//  Sample usage:
//
//   myView.frameX += 10;  // Move 10 points right.
//   [myView addCenteredSubview:aSubView];
//
