I think this is a reasonable idea - what's been before is
prelight for menu bar menu items .. (Windows 95, 98, etc, 
have mouse-over for menus.)

It would have to be a style property since suddenly passing the
PRELIGHT state to the code in existing themes to draw notebook
tabs will not work.

Unfortunately, I can't really give you much advice on implementation,
it's basically just "implement it the same way as other mouse handling
and style properties are implemented in other widgets"

I'd guess it would take an experienced GTK+ hacker an hour or two
to do, a inexperienced GTK+ hacker longer. How much longer is
hard to estimate.
