 * A small utility class which can be used to mimic the DefaultXXXRenderer behaviour for custom renderer
 * implementations. Basically, it offers methods for tables, lists and treetables, which expose the same signature as
 * the according renderer interface, with the addition of a JComponent. The specified component will be configured in
 * the same way as the default renderer implementation regardings fonts, borders and such.
