Actually, it IS an array, but by convention of the built-in fonts (not
mentioned in the RedBook...  (did I mention that already?)) an
EXECUTABLE array.  So if you do something like:

	/Times-Roman findfont begin FontBBox

the interpreter will EXECUTE the array.  Executing an array containing
4 numbers is equivalent to pushing them on the stack.  So all the
implementations are right.  Some PS code uses this feature to be more
concise (probably not significantly more efficient).

To get the array itself, try:

	/Times-Roman findfont /FontBBox get
