GtkPaned patch

[Luis Oliveira <luismbo netcabo pt>]

Hi, 

I'm a GTK+ newbie, I'm trying to add a new property to GtkPaned, a
"continuous" property that decides if there should be constant redrawing
when dragging a GtkPaned. 

My patch works, but I'm not sure if this is the best way to do it and it
is missing a visual way of telling the user where it will get dragged
to. I have no idea how to do this, I was hoping someone would give me a
clue :) 

TIA
