implementation on OS/2:

Let me ask differently: Does any code of the canvas implementation rely
on system coordinates to start at the top left (while under OS/2 the
origin in the _bottom_ left)? I looked through the code again a bit, but
maybe I was too tired.
If nobody here can answer this where should I post instead? (There is no
canvas newsgroup.)
