/* We basically duplicate the Mule vectors-of-vectors implementation.
We can do this because we know a great deal about the sorts of
things we are going to be indexing.
The current implementation is as follows:
ascii[0-159] is used for ASCII and Control-1 characters.
level1[0 .. (NUM_LEADING_BYTES-1)] indexes charsets by leading
byte (subtract MIN_LEADING_BYTE from the leading byte). If the
value of this is not an opaque, then it specifies a value for all
characters in the charset. Otherwise, it will be a
96-Lisp-Object opaque that we created, specifying a value for
each row. If the value of this is not an opaque, then it
specifies a value for all characters in the row. Otherwise, it
will be a 96-Lisp-Object opaque that we created, specifying a
value for each character.
NOTE: 1) This will fail if some C routine passes an opaque to
Fput_char_table(). Currently this is not a problem
since all char tables that are created are Lisp-visible
and thus no one should ever be putting an opaque in
a char table. Another possibility is to consider
adding a type to */
