Right now encoding and decoding images requires a lot of extra memcpys since 
the encoder and decoder are only written to interact with 4x4 RGBA buffers.  
Ideally it would be nice to pass an optional stride argument in, so images can 
be compressed and decompressed without using intermediate RGBA block buffers.

Adding this to the decoder is very easy (patch attached), but adding it to the 
encoder looks a bit trickier.
