If you have sufficient encapsulation of the text layout and rendering
portions, it's not hard; there are maybe 30 lines in gtkentry.c (out
of 4200) to handle rendering "password" entries correctly.

Plus, as compared to using a special font, GTK+ offers the ability
to set the replacement character or to not draw anything at all.

The "secret" is just to avoid putting text drawing and measuring code
all over the control; this helps with a lot of other things as well.
