gzdoom-gles/src/p_doors.cpp
Christoph Oelckers 9a410f864f - Separated the linedef activation types into a bit mask that allows combination
of all types on the same linedef. Also added a 'first side only' flag. This
  is not usable from Hexen or Doom format maps though but in preparation of
  the UDMF format discussed here:
  http://www.doomworld.com/vb/source-ports/43145-udmf-v0-99-specification-draft-aka-textmap/
- Changed linedef's alpha property from a byte to fixed point after seeing that
  255 wasn't handled to be fully opaque.
- fixed a GCC warning in fmodsound.cpp
