	A "Style" (or technically, the GtkEtextStyle) is currently just a
linked list of Pango attributes.  It would be possible to add whatever you
wanted to the list, but you'd need to write extra code in the "View" to
handle non-Pango attributes.

	The feature you mention is one I plan to implement in my
application :).

	A Style can have as many attributes as you like (including a
pointer to a callback function of some kind), but some of this may be
better implemented with "Tags", which are overlapping.  I have not yet
implemented tags in my widget, although it is planned.

	I need to write the "View" first, and then see where these
features would fit in.  But, I *do* wish to add features like the ones you
describe.  I just don't know if they belong in the widget or in the app,
yet.
