// most of the information will be in its children, which can be any of the following

// ENVPALET

// RIFCHILD(s) - the name of RIF file(s)
//	   this is basically a RIF_Name_Chunk, but named differently so as to distinguish it from its own file's name
//     which should have a REBENVDT chunk with BMPNAMES and/or RIFCHILD(s) (even more RIFs)
//     specifying what non-environment specific bitmaps are used, and probably much more data,
//         - they could be sprites, etc.
//     then all the data could be automatically included (but not loaded) by the inclusion of one file

// ENVTXLIT - texture lighting table,
//     but maybe this should a filename to load if required

// CLRLOOKP - 15-bit r;g;b lookup table to get palette entries for coloured polygons on load
//     can have a table or a reference file

// other relevant chunks to be added later
// we may need some sort of BMPNAMES chunk, for flags about which bmps are quantized, etc.
