2005/09/01 14:01:29 thb 1.2.34.1: #122302# Using new Shape::getDOMBounds() method to determine size of the clip polygon, instead of the former getUpdateArea(). This is because, the sprite clip is transformed by the sprite transformation, which in turn contains the _full_ shape transform, relative to the DOM values
