OK.  You could do this either directly with Gdk drawing primitives or
using libcairo (which we already indirectly depend upon through gtk).
I think the cairo option would  make a lot of future issues easier
(like vertical labels in graphs/tables, producing PDF output etc.).
It also avoids worry about some of the lower level issues involved
with Gdk (like using the write GdkStyle and GdkGC) which I still don't
fully understand after decade or so of reading about them.

Also, I think Libcairo could replace libplot and offer a number of
improvements.
