It may use the same calculations as the hardware renderer but must use the 2D drawer for display.
It should be investigated if the hardware renderer can do this as well.
It now works the following way:
(0) - Force off (ZDoom defaults)
(1) - Force on (Doom defaults)
(2) - Auto off (Prefer ZDoom defaults - if DEHACKED is detected with no ZSCRIPT it will turn on) (default)
(3) - Auto on (Prefer Doom defaults - if DECORATE is detected with no ZSCRIPT it will turn off)
Both files can now be included independently without causing problems.
This also required moving some inline functions into separate files and splitting off the GC definitions from dobject.h to ensure that r_defs does not need to pull in any part of the object hierarchy.
- replaced some uses of FRACUNIT with OPAQUE when it was about translucency.
- simplified some overly complicated translucency multiplications in the SBARINFO code.
