Equivalent to low-level text draws

["Mark Tilford" <ralphmerridew gmail com>]

I'm trying to port a Windows program.  It has its own text layout
written in portable code, so I only need to handle things like
draw_text_at (xcoord, ycoord, string, font) and measure_text (string,
font).  Where's the appropriate documentation?

(And it needs raw measuring; "<B>x</B>" should render / be measured as
8 characters, not 1.)


BTW, why is Cairo even mentioned in
http://gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch15.html if it was
apparently added in gtk 2.9?
