I suppose fiddling with the style of the seperator could probably produce a red line also...  Perhaps I need 
to rip the guts out of GtkHSeparator, and put together a "thin red line" widget...  ;)

Does anyone know what kind of overhead considerations exist for a widget within the text buffer?  Would a 
h-line widget be "cheaper" than an image or a stack of very small writing with red forground and background 
colours?

True enough...  Could get sticky if there's several of them though...

As I understood it from somewhere, you can ask to be allowed to draw markers and so forth down the sides, 
though I've never been able to find the mechanism to do it.

Is there any facility, other than embedding a GtkDrawingArea or your own widget, to create a stripe across 
the page that you will recieve expose events for, and can simply colour red?  Or is that exactly what the 
widget embedding facility is?
