Subject: no more "correct offsets" in particle engine
X-Git-Url: http://deadsoftware.ru/gitweb?a=commitdiff_plain;h=c21a8185eec05fa8e15d243ef475888c8d9cd699;p=d2df-sdl.git

no more "correct offsets" in particle engine

  previous ray tracer was bugged: it could return position inside wall,
  so particles were trying to "compensate" for that (wrongly). and they
  were doing it on *each*(!) think step.

  as particles are pure eye candy (and i rewrote ray tracer), i removed
  that "compensator" altogether.
