/**
* JXHeader is a simple component consisting of a title, a description,
* and an icon. An example of such a component can be seen on
* Romain Guys ProgX website
*
* JXHeader is a simple component that is also sufficiently
* configurable to be usable. The description area
* accepts HTML conforming to version 3.2 of the HTML standard. The icon, title,
* and description are all configurable. JXHeader itself extends
* {@link JXPanel}, providing translucency and painting delegates.
*
* If I were to reconstruct the ui shown in the above screenshot, I might
* do so like this:
*
* JXHeader header = new JXHeader();
* header.setTitle("Timing Framework Spline Editor");
* header.setDescription("Drag control points in the display to change the " +
* "shape of the spline\n" +
* "Click the Copy Code button to generate the corresponding Java code.");
* Icon icon = new ImageIcon(getClass().getResource("tools.png"));
* header.setIcon(icon);
*
*
* Note: The HTML support doesn't exist yet. The UI delegate needs to discover whether
* the text supplied is HTML or not, and change the content type of the editor pane
* being used. The problem is that if "text/html" is always used, the font is wrong.
* This same situation will be found in other parts of the code (JXErrorPane, for instance),
* so this needs to be dealt with.
*
* Defaults
* BasicHeaderUI uses the following UI defaults:
*
* - Header.defaultIcon: The default icon to use when creating a new JXHeader.
