// 1.13.2002 mcn - Created. //
// //
//// Notes ////////////////////////////////////////////////////////////////////
// //
// If you add a new PlasmaMAXLayer type, you need to add the appropriate //
// test in ConvertTexmap() as well as your own function to do the //
// conversion. Messy, but thanks to the dependencies of the convert process,//
// we can't do it the nice, pretty, OOP way. //
