Author	SHA1	Message	Date
Peter Amrehn	bbfdff7670	move some methods from LosslessDecoder to base class Implementing WebPLossyDecoder.DecodeAlphaData these methods are called from there containing the same code than in the lossless decoder, so we move them to an abstract base class. (not sure if it's a good idea to move the BitReader itself as well, so passing it as a parameter for now)	7 years ago
