Cairo has an image backend, which is usually used for both on-screen rendering and which also supports saving to a file. When displaying on- screen the default is most probably fine -- Cairo gets its subpixel rendering settings from the OS (fontconfig on Linux) so all is well. However, when saving to a file, depending on its intended use one may either want to enable/disable subpixel antialiasing/rendering. If it is intended for print you probably want to disable it, however, for web graphics subpixel rendering is extremely common. Furthermore Cairo also has provisions for subpixel antialiasing for line art. (So the same techniques which are applied to text are also applied to polygons, curves &c.) While none of the backends currently make use of it, it is quite likely that in the future the image backend will support it. Therefore a general subpixel antialiasing setting might be a better bet. I would therefore suggest having two options: one for when printing and another for displaying on screen. The default for printing/saving should probably be off, while the displaying should be got from the system.
