gzdoom-gles/src/r_translate.cpp
Randy Heit 5b8055bfc7 - Since KDIZD is the only mapset I know of that used reverb, and it didn't 
define any new ones of its own, I'm pre-emptively renaming the SNDEAX lump
  to REVERBS to remove any possible misunderstanding that this is something
  that requires EAX hardware support. (Ideally, it would have been REVERBDEF,
  but that's 10 characters long.) The eaxedit console command has also been
  renamed to reverbedit for the same reason.
- Fixed: The Palette part of FRemapTable was not initialized with alpha values
  other than 0. I'm not sure if it would be better to fix this in the game
  palette that it copies from or not, but right now, they get set
  unconditionally to 255.
