using the same coordinates as al_draw_line - so no need to change it. 
I'd even prefer al_draw_ellipse to use the bounding box coordinates but 
it can be argued that it should behave like al_draw_circle.

By the 'same coordinates' do you also mean same sense of exclusivity? I 
want to try to make both coordinates of al_draw_line to be inclusive 
(like in A4). Does this mean you now support the bottom right rectangle 
coordinates to be inclusive also?
