Is this already possible in the current version of tioga? It was not  
mentioned at all in the documentation that I could find.

 From reading the documentation I already gathered it had something to do  
with clip_to_frame, but was kinda afraid that show_plot would turn out to  
be quite complicated. Luckily, it is quite simple and easy to follow :) I  
ended up just doing the whole thing without clip_to_frame, by rewriting:

t.show_plot( mybounds ) do
	...
end

to:

cmd = Proc.new do
	...
end
t.set_bounds( mybounds )
t.context { cmd.call( self ) }
t.show_plot_box

That worked perfectly. (I think I am now calling cmd with another "self",  
but since I am not using it within the block anyway that does not matter  
in this case.)

Cheers,
