Code: added gesture component palm up, added a new hand model that
stores context such that one can watch for a change of hand to palm up
and then have a reverse threshold that it must pass before it can return
a palm down. Added ability for themed images/vector images to be used
with circle menus, added some code in preparation for multi-touch with
circle menus.

unintentional strikes upon exit.
