(v13) flush in the PFIN API

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

sw_pfin_result flush(int uniqueid, const sw_datum * glyphname);

This call allows the module to remove a glyph or an entire font from the font cache. This is a highly unusual action, but may be required to allow module-specific configuration, that would change glyph generation, to produce consistent output.
