 * object is accepted, however anything but strings and
 * arrays is ignored (and text drawing turns blank).
 * Single strings are interpreted as font family names,
 * and directly passed to the underlying C++ object;
 * arrays however are searched for the first string
 * object corresponding to a valid font family name,
 * and rendering is done with that. In mkxp, we pass
 * this first valid font family as the 'name' attribute
 * back to the C++ object on assignment and object
 * creation (in case Font.default_name is also an array).
 * Invalid parameters (things other than strings or
 * arrays not containing any valid family name) are
 * passed back as "". */
