raze/polymer/eduke32/build/include/polymost.h
helixhorned bd0febb846 In non-lookup OpenGL modes, make sector[].filler (rename pending) override fogpal. 
That is, if that member has a nonzero value, that one is taken for the color of
the GL fog instead of (most of the time) sector[].floorpal. "Sky sectors", that
is, skyboxes or simply parallaxed floors/ceilings are *not* handled.
