6685256560 change STBVOX_MAKE_LIGHTING to STBVOX_MAKE_LIGHTING_EXT so header file 
doesn't have to see the config variables (although this way is actually
more bug prone since you can now use the wrong macro)

c588d29e95 switch shader variation from runtime-with-tags to dynamic with #ifdefs; 
support making all definitions static so you can have multiple copies of file (with different #ifdefs);
move all tables to end of file (this will have to be undone later because IIRC it's not compatible with C++ or with some compilers or something, but it'll make my life easier in the interim);

optimize subtraction of STBIR_ALPHA_EPSILON;
