(v13) Parametric PFIN fonts

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP

Because of the find entry point, a PFIN module instance may choose to parse font names, rather than merely recognize them. This allows modules to implement parametric fonts, such as multiple-master style fonts where axis values are specified as part of the font name, or even to generate obliques and different weights algorithmically from the fontname style postfix. Alternatively, a font emulation module could define missing fonts on demand, defining whatever parameters are necessary to emulate that font as its PFID.
