Is the rendering intent hard-coded in Poppler or in the pdftoraster 
filter? Or can the problem be fixed by the pdftoraster filter directly 
communicating with the liblcms stuff? If it requires changes in Poppler 
we should report a bug in Poppler ASAP and it is a bug of high impact as 
it makes Poppler's color management very restricted.

If it is possible to fix it in pdftoraster, then, Otani-san, could you 
fix it?
