+    /** Some fonts are stored in files. If that is true for the fontID, then
+        this returns the byte length of the full file path. If path is not null,
+        then the full path is copied into path (allocated by the caller), up to
+        length bytes. If index is not null, then it is set to the truetype
+        collection index for this font, or 0 if the font is not in a collection.
+
+        Note: getFontPath does not assume that path is a null-terminated string,
+        so when it succeeds, it only copies the bytes of the file name and
+        nothing else (i.e. it copies exactly the number of bytes returned by the
+        function. If the caller wants to treat path[] as a C string, it must be
+        sure that it is allocated at least 1 byte larger than the returned size,
+        and it must copy in the terminating 0.
+
+        If the fontID does not correspond to a file, then the function returns
+        0, and the path and index parameters are ignored.
+
+        @param fontID  The font whose file name is being queried

+                       of the font's file name. Allocated by the caller.
+        @param length  The maximum space allocated in path (by the caller).
+                       Ignored if path is NULL.
+        @param index   Either NULL, or receives the TTC index for this font.
+                       If the font is not a TTC, then will be set to 0.
+        @return The byte length of th font's file name, or 0 if the font is not
