 * On-screen display symbols for various things.  These do not include
 *  things like objects - basically, if it can ever move, it shouldn't
 *  be one of these.
 *
 * For the sake of clarity when investigating bugs, the _UNKN_ symbols
 *  should be (a) all distinct from one another and (b) entirely
 *  disjoint from the non-_UNKN_ symbols.  The code will not break if
 *  this is violated, but debugging output may be ambiguous.
