A corner-stretchable UIImage class

The UIImage should stretch itself to the specified corners. The corners can be x,y relative to its superview. Example image: [login to view URL] Example class interface: @interface StretchabeImage : UIView{ int top_left; int top_right; int bottom_left; int bottom_right; } @end When done I'd prefer you make a video of it in action, showing 20-50 images with each of their corners moving randomly +- 5-10 pixels each loop.
