Actually, Gecko doesn't even have that.  The preloader code runs before 
the viewport size is known, for example.

Furthermore, in an ideal world the preloader would run on a totally 
separate thread from any of the CSS/layout/etc stuff.  So adding any 
dependencies from the preloader on it is really not OK.
