No Alex, that won't do.  The fact that users won't render paper output 
this way doesn't matter; what matters is that for some users, the "print 
preview" must be themed rather than WYSIWYG.

The print preview mechanism MUST be theme-aware, or at least themeable 
(i.e. fg and bg colors must be speciable via the theme).  This is a 
"hard" (i.e. firm) accessibility requirement, I didn't make it up :-)

Bill
