raze-gles/polymer/eduke32/build/src/polymer.c
helixhorned 7b6bf4dda2 Lunatic: new-generation map format, in-memory representation ("map-int VX"). 
The Lunatic build compiles with new structures for sector and wall types.
They have separate members for TROR {up,down}{bunch,nextwall}, so there are
no conflicts with other uses of members into which they were previously
shoehorned.  Also, the maximum bunch limit is bumped to 512 in that build.

Currently, loading from V7/8/9 and saving to V7 and V8 are supported.
