/* Composite characters are characters constructed by overstriking two
   or more regular characters.

   1) The old Mule implementation involves storing composite characters
      in a buffer as a tag followed by all of the actual characters
      used to make up the composite character.  I think this is a bad
      idea; it greatly complicates code that wants to handle strings
      one character at a time because it has to deal with the possibility
      of great big ungainly characters.  It's much more reasonable to
      simply store an index into a table of composite characters.

   2) The current implementation only allows for 16,384 separate
      composite characters over the lifetime of the XEmacs process.
      This could become a potential problem if the user
      edited lots of different files that use composite characters.
      Due to FSF bogosity, increasing the number of allowable
      composite characters under Mule would decrease the number
      of possible faces that can exist.  Mule already has shrunk
      this to 2048, and further shrinkage would become uncomfortable.
      No such problems exist in XEmacs.

      Composite characters could be represented as 0x80 C1 C2 C3,
      where each C[1-3] is in the range 0xA0 - 0xFF.  This allows
      for slightly under 2^20 (one million) composite characters
      over the XEmacs process lifetime, and you only need to
      increase the size of a Mule character from 19 to 21 bits.
      Or you could use 0x80 C1 C2 C3 C4, allowing for about
      85 million (slightly over 2^26) composite characters. */

Define a new character set.
This function is for use with Mule support.
NAME is a symbol, the name by which the character set is normally referred.
DOC-STRING is a string describing the character set.
PROPS is a property list, describing the specific nature of the
character set.  Recognized properties are:

'short-name     Short version of the charset name (ex: Latin-1)
'long-name      Long version of the charset name (ex: ISO8859-1 (Latin-1))
'registry       A regular expression matching the font registry field for
                this character set.
'dimension      Number of octets used to index a character in this charset.
                Either 1 or 2.  Defaults to 1.
'columns        Number of columns used to display a character in this charset.
                Only used in TTY mode. (Under X, the actual width of a
                character can be derived from the font used to display the
                characters.) If unspecified, defaults to the dimension
                (this is almost always the correct value).
'chars          Number of characters in each dimension (94 or 96).
                Defaults to 94.  Note that if the dimension is 2, the
                character set thus described is 94x94 or 96x96.
'final          Final byte of ISO 2022 escape sequence.  Must be
                supplied.  Each combination of (DIMENSION, CHARS) defines a
                separate namespace for final bytes.  Note that ISO
                2022 restricts the final byte to the range
                0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if
                dimension == 2.  Note also that final bytes in the range
                0x30 - 0x3F are reserved for user-defined (not official)
                character sets.
'graphic        0 (use left half of font on output) or 1 (use right half
                of font on output).  Defaults to 0.  For example, for
                a font whose registry is ISO8859-1, the left half
                (octets 0x20 - 0x7F) is the `ascii' character set, while
                the right half (octets 0xA0 - 0xFF) is the `latin-1'
                character set.  With 'graphic set to 0, the octets
                will have their high bit cleared; with it set to 1,
                the octets will have their high bit set.
'direction      'l2r (left-to-right) or 'r2l (right-to-left).
                Defaults to 'l2r.
'ccl-program    A compiled CCL program used to convert a character in
                this charset into an index into the font.  This is in
                addition to the 'graphic property.  The CCL program
                is passed the octets of the character, with the high
                bit cleared and set depending upon whether the value
                of the 'graphic property is 0 or 1.
