- Fixed: Fog for flooding floor textures into gaps created by missing wall textures

didn't work since a parameter changes necessitated by ZDoom's render style 'enhancement'.

Update to ZDoom r940:

  SBarInfo Update #18:
- Simplified the DrawGraphic function in sbarinfo_display.cpp
- Added xOffset, yOffset, and alpha to every drawing function in
  sbarinfo_display.cpp.  So Strife popups can be handeled better and allow for
  other effects (translucent bars?).  I'm thinking about making a struct for
  these five (also x and y) arguments so that the argument lists don't become a
  mess.
- Changed DRAWIMAGE in sbarinfo_display.cpp to not use so many calls to
  DrawGraphic.
- DrawKeyBar wasn't using screen->DrawTexture.
- Added a Fade transition for popups.  It takes two args fade in rate and fade
  out rate.  Both are floats (1.0 = 1 tic to complete 0.5 = 2 tics to complete
  and so on).
- Added a translucency arg to statusbars.  1.0 = opaque and 0.0 = invisible.

- Fixed: When an instrument's envelope runs out, it does not immediately ramp
  to zero. Rather, it lets the remainder of the sample finish playing.
- Fixed: When playing a MIDI file with EMIDI track designations to turn a
  track off, any ticks that had only events on the disabled track would cause
  the delay for that track to be thrown away, and the following notes on
  enabled tracks would play too soon. This could be heard quite clearly in
  xplasma.mid, where track 4 (FMGlass Drone 1) would interfere with the timing
  of tracks 13 and 14 (EP1 Melody and EP1 Echo).
- Fixed: DFlashFader did some operations in its destructor that had to be moved
  to its Destroy method.
- Fixed: Dropped weapons from dying players should not double ammo.
- Fixed: When note_on() is called and another copy of the same note is
  already playing on the channel, it should stop it with finish_note(), not
  kill_note(). This can be clearly heard in the final cymbal crashes of
  D_DM2TTL where TiMidity cuts them off because the final cymbals are played
  with a velocity of 1 before the preceding cymbals have finished. (I wonder
  if I should be setting the self_nonexclusive flag for GUS patches to
  disable even this behavior, though, since gf1note.c doesn't turn off
  duplicate notes.)
- Changed envelope handling to hopefully match the GUS player's. The most
  egregious mistake TiMidity makes is to treat bit 6 as an envelope enable
  bit. This is not what it does; every sample has an envelope. Rather, this
  is a "no sampled release" flag. Also, despite fiddling with the
  PATCH_SUSTAIN flag during instrument loading, TiMidity never actually
  used it. Nor did it do anything at all with the PATCH_FAST_REL flag.
- Fixed: wbstartstruct's lump name fields were only 8 characters long
  and not properly zero-terminated when all 8 characters were used.
- Fixed: Local sound sequence definitions caused a crash because a proper
  NULL check was missing.
- Added translucent blending modes to FMultipatchTexture (not tested yet!)
- Also changed all true color texture creation functions to use proper alpha
  values instead of inverted ones.
- Changed FRemapTable so that all palette entries must contain proper alpha
  values. 
- Fixed: The F1 screen check in m_menu.cpp was missing a NULL pointer check.
- Changed: The boss brain's explosions play weapons/rocklx which is an 
  unlimited sound. This can become extremely loud. Replaced with a new
  sound which is just an alias to weapons/rocklx but has a limit of 4.
