Who ever had this idea to scale image data just in case of jpx streams to 8 bit
values but then treat index values in the reading function? This prevents a
clean solution, in my eyes every solution looks like a dirty hack...

And because getImageParams() is called so early which already reads the jpx
data and scales it I even have not yet the Gfx colorspace which is parsed
later.
