/* Let's talk about references. */
/* If we are doing Type1 output, then the obvious way of doing them is seac */
/*  but that's so limitting. It only works for exactly two characters both */
/*  of which are in Adobe's Standard Enc. Only translations allowed. Only */
/*  one reference may be translated and the width of the char must match */
/*  that of the non-translated reference */
/*   The first extension we can make is to allow a single character reference */
/*  by making the other character be a space */
/*   But if we want to do more than that we must use subrs. If we have two */
/*  refs in subrs then we can do translations by preceding the subr calls by */
/*  appropriate rmovetos. Actually the specs say that only one rmoveto should */
/*  precede a path, so that means we can't allow the subroutines to position */
/*  themselves, they must just assume that they are called with the current */
/*  position correct for the first point. But then we need to know where the */
/*  first point should be placed, so we allocate a BasePoint to hold that info*/
/*  and store it into the "keys" array (which the subrs don't use). Similarly */
/*  we need to know where the subr will leave us, so we actually allocate 2 */
/*  BasePoints, one containing the start point, one the end point */
/*   But that's still not good enough, hints are defined in such a way that */
/*  they are not relocateable. So our subrs can't include any hint definitions*/
/*  (or if they do then that subr can't be translated at all). So hints must */
/*  be set outside the subrs, and the subrs can't be for chars that need hint */
/*  substitution. Unless... The subr will never be relocated. */
/*   So we generate two types of reference subrs, one containing no hints, the*/
/*  other containing all the hints, stems and flexes. The first type may be */
/*  translated, the second cannot */
/* Type2 doesn't allow any seacs */
/*  So everything must go in subrs. We have a slightly different problem here:*/
/*  hintmasks need to know exactly how many stem hints there are in the char */
/*  so we can't include any hintmask operators inside a subr (unless we */
/*  guarantee that all invocations of that subr are done with the same number */
/*  of hints in the character). This again means that no char with hint subs- */
/*  titutions may be put in a subr. UNLESS all the other references in a */
/*  refering character contain no hints */

/* That's very complex. And it doesn't do a very good job. */
/* Instead let's take all strings bounded by either moveto or hintmask operators */
/*  store these as potential subroutines. So a glyph becomes a sequence of    */
/*  potential subroutine calls preceded by the glyph header (width, hint decl,*/
/*  counter declarations, etc.) and intersperced by hintmask/moveto operators */
/* Each time we get a potential subr we hash it and see if we've used that    */
/*  string before. If we have then we merge the two. Otherwise it's a new one.*/
/* Then at the end we see what strings get used often enough to go into subrs */
/*  we create the subrs array from that.				      */
/* Then each glyph. We insert the preamble. We check of the potential subroutine */
/*  became a real subroutine. If so we call it, else we insert the data inline*/
/*  Do the same for the next hintmask/moveto and potential subroutine...      */

/* Then, on top of that I tried generating some full glyph subroutines, and   */
/*  to my surprise, it just made things worse.                                */
