Well, maybe the following may count as "any help" :-) 1) gdk_draw_arc is about drawing (segments of) elipse, while the "replacement" cairo_arc is about (segments of) circles and applying some translation to it. For an example see: http://developer.gnome.org/gtkmm-tutorial/3.0/sec-cairo-drawing-arcs.html.en and http://www.cairographics.org/manual/cairo-Transformations.html 2) All use cases in this file are from 0 to 360 degrees, so this paints a full elipse (and from now on circles). So maybe the "easy" way out would be to rename ELMT_ARC to ELMT_ELIP and draw a scaled filled circle and be done with it.
