An 1- 2- 4- and 8-bit AVI is palettized no matter if it contains a 
palette or not. Of course it has to contain palette in order to display 
it correctly, but in the case of 1 bpp I have set a default black & 
white palette in raw_init_decoder() to avoid sudden surprises when 
switching from using monow.
