<p>The following types and functions are used to manage Multiple Master fonts, i.e. the selection of specific design instances by setting design axis coordinates.</p>
<p>George Williams has extended this interface to make it work with both Type 1 Multiple Masters fonts, and GX distortable (var) fonts. Some of these routines only work with MM fonts, others will work with both types. They are similar enough that a consistent interface makes sense.</p>
