There are a few animations with start frame >= 0 and also >= framecount It seems that for such animations, the decoder is supposed to start at 0 and play framecount number of frames. So for these cases we deduct a _startFrame ammount before sending them to decoder. This addresses crash bug #14438 PINK: Crash in Egypt when using the digger on the characters for Passport to Peril Also, set startFrame to 0 for non-standard animations
