/**
 * This class is a subclass of QLabel that provides gradient Elide support.
 * It properly supports rich text in the underlying QLabel.
 * 
 * It does this by forcing the underlying QLabel to draw itself onto a pixmap
 * and then compositing this pixmap with a transparent gradient.
 * 
 * It will only draw the gradient if the text width exceeds the width of the label.
