Correct handling of bitmap images

I've attached a patch that works correctly for me whether the pdf image has or
has not a /Decode array. For the sake of efficiency on large scans my fix only
peeks at the colormap to decide what xor mask to use. The bit stream is then
processed without involving the normal gary/color handling functions.
