I always wished tooltips would be less boring, and so we have them all
fancy and nice :-)
* tooltip theme can request a timeout before hiding. This means we
can fade out the tooltips nicely.
* tooltip theme get enough information to track its origin. The
current theme will show a small tip where it was created, and
dynamically follows it. The graphics kinda suck, but I tried to
achieve a cartoon-like buble using Inkscape.
* label style is set to "tooltip". I'm providing a default with
dark-gray text and 8 as size.
