I'm pretty sure you need to change the resolution of the IDLgrBuffer so
it matches your screen resolution. The default DPI is 72 which is
usually not your window manager's DPI. I think MS Windows is 96 by
default but I don't know. You can run 'xdpiinfo' (?) on x-windows based
machines to see what your DPI is (or something like that, I'm on a
windows box now so I can't check).
