well the REDAME is a little dated, the header files there use:

#define MAXPLANES       50      /* Maximum number of planes per cell */
/* jws allow 225 types */
#define TT_MAXTYPES             225                     /* See above! */

but note that the above MAXPLANES doesn't change the builtin tile
type plane limit of 25 (MAXPLANES is something else)
