[XeTeX] cmyk colour support broken?

[Jonathan Kew]

Will -

If you'd care to build a copy of the latest XeTeX code from  
Subversion, you'll get a version of xdv2pdf where I have revised the  
color support to use CGColor values with the proper colorspace  
settings, so you may find that CMYK colors work better. (This also  
applies to the dvips-style named colors, if anyone uses those, as  
they're specified with CMYK values in the code.)

I don't really know much about how Quartz will represent these in the  
resulting PDF, but at least it has a better chance of doing the right  
thing now. Looking into a simple PDF, I see that it does pass RGB/ 
CMYK/Gray colorspaces through in some form, depending on the \special 
{color ...} used, so that's a good sign.

I'd appreciate knowing if this helps. Thanks!
