CSS Font size in points doesn't match Node.Font.Size

[Kevin Rushforth]

I don't think we can do what you suggest about the warning, since there 
are cases where CSS could be initialized prior to calling into the 
application (e.g., the default preloader, deploy dialogs), but I think 
it might make sense to add a property to control the scale. Can you file 
a JIRA request for adding such a property?

I think we can argue separately whether it should be the default at some 
point, but I am not in favor of that. This would be too big of a 
breaking change.
