ignore the alternateSpace and tintTransform

As a reasonable compromise in my eyes this new patch now also checks the
alternate colorspace, and if this is DeviceGray in case of a separation
colorspace with name black this patch treats is as if it is really a DeviceGray
and so ignore tintTransform and alternate colorspace just in this case when
using getGray() and getRGB().

This also removes all unexpected failures in my regression test, but still
shows the text with pdftoppm or in evince or in okular. If You still don't
agree, please feel free to remove the changes in getGray() and getRGB(), but
commit the changes in getCMYK() because the changes in getCMYK() are following
the spec!
