If done right, the code doing coordinate conversion should be in library
Canvas class, not in application code.
That's how I would have implemented in it fpGUI as well. The higher
level code uses x, y as normal. The drawing backend code does
conversions if needed.
That's how I handle differences between Windows GDI API and XLib API.

Very good points, and I completely agree :)
I was only doing a quick "hack" so I could get something working in a short
time ;)
BTW, I found these very interesting articles about IMGUI (Immediate Mode
GUI) systems (which I am using in my game):
http://www.johno.se/book/imgui.html
http://sol.gfxile.net/imgui/index.html
and a forum about IMGUs
http://www.mollyrocket.com/forums/viewforum.php?f=10
Perhaps this might help someone, except maybe Graeme "fpGUI" Geldenhuys LOL!
;P
cheers,
Paul
