[texworks] Poppler problem

[Geoff Vallis]

 From my perspective it is not especially urgent, as it seems that one  
can always embed the fonts by opening the file in Preview and using  
'save as'. But eventually, if TeXworks is to become a 'production- 
level product, it seems like it should be able to handle non-embedded  
base fonts.
