Find an object with the given CollisionLayers bits set at that location.
If you specify multiple bits, it finds one with any of those bits. (It
is not possible for there to be more than one such object.)
ObjTopAt ( x y -- obj )
Find the object on the top at the specified location. The result will be
zero if that location is vacant or out of range.
oz? ( any -- bool )
True if the value is an object or zero, or false if it is neither an
object nor zero. (Even if the object has been garbage collected, it is
still true.) Error if it is a sound.
pick ( index -- any )
