  GraphicsMagick types typedefs.

  GraphicsMagick is expected to compile with any C '89 ANSI C compiler
  supporting at least 16-bit 'short', 32-bit 'int', and 32-bit 'long'.
  It is also expected to take advantage of 64-bit LP64 and Windows
  WIN64 LLP64.  We use C '99 style types but declare our own types so
  as to not depend on C '99 header files, and take care to depend only
  on C '89 library functions, POSIX, or well-known extensions.  Any C
  '99 syntax used is removed if the compiler does not support it.
