// font to list in the private data for future reference.

// allow for different facenames, and also doesn't do a mapping
// between 'standard' facenames (e.g. Arial, Helvetica, Times Roman etc.)
// and the fonts that are available on a particular system.
// Maybe we need to scan the user's machine to build up a profile
// of the fonts and a mapping file.
// Return font struct, and optionally the Motif font list
