-- added smacker lib to makefile and sgp/smacker
-- first version with some output .. correctly decodes smacker files
   files need to be extracted from intro.slf and placed in direcory intro
-- first working decoder
- Video is working (640x480 - fixed...)
  for the moment only extracted SMK files work.
  Audio has to handled
  Fixed method to convert Image into Buffer.
-- green color was shifted 2 times too many (div 4, not shift 4 -> shift 2)
-- minor cleanups
-- added RGB 555 mode
-- started to support smack audio
-- make SMK_MODE_DISK working
-- honor x/y offsets for display
-- added primarily sound support loading audio data first into a buffer
   need a method to play audiobuffer
some more fuzzing with sound..
-- got audio to work properly
   but leaks a bit and is not in sync with video...
   actually video is behind?
slight improvement
-- smk files have to be in intro/ directory
-- need to find a way to make video/audio sync
-- some optimization for filling FRAME_BUFFER
-- X and Y were confused before
Fix compilation with Visual Studio 2010
-- unified type definitions
-- merged Gennady Trafimenkov a6fc459 Windows build patch
-- corrected left channel only output (what is a good value for panning)
-- most videos in synch
-- audio/video in sync (if video does not lag behind...)
-- less audio buffer allocated (and probably the right amount too)
-- strange sound problem at intro but rest exact in sync
-- for testing. audio/video SHOULD be in sync, even if video lags behind a bit
-- intro sound seems to have a problem though (either through decoder or data)
-- better handling of lagging video
