doxygen discovers HUD controls?

Browsing through the new versions of the documentation stuff I noticed Doxygen has magically uncovered a whole folder full of HUD controls that I've never seen in my copy of the engine =) Are these being released in an updated version of the engine.. are they in the (current private) CVS repository... is it a mistake.. or what?

Just curious as I'd love to add a Bezier curved health/energy display to my HUD ;)

Regardless, much more informative than the alpha Docs, keep up the good work
