All fonts include a 'dpi' parameter which only changes the rendering size without changing any of the other characteristics. In the current SVN version, the font_rep class also contains a method 'zoom' which you can use to magnify a font (the method returns the zoomed font). Hence, in order to transform a font which was correctly on a 72dpi screen on a 144dpi retina screen, just apply a zoom factor 2.0 before rendering. For better performance, you may also consider doubling the zoom factor associated to the window (instead of applying the window zoom and then the retina zoom).
