For X11, using the ordinary cursor up the maximum size is obvious; whether
then to use a masked pixmap or chain of line segments is a matter of
benchmarking under different circumstances (remote vs local X server,
different server cleverness etc).
For instance, a masked pixmap requires little bandwidth once it has been
transferred to the server, but might be slow if the server handles sparse
masked blits in a bad way. Line segments need more bandwidth per mouse
motion but are potentially cheaper to render. Implementing either is not
hard, but I (being primarily an Xlib programmer) don't know how if gdk/gtk
have the necessary primitives
