 Adds cairo-based terminals for pdf and png targets.  Works around ticket
 #27892.  May also enable features in combination with wxWidgets variant?
 (wxt terminal: http://lwn.net/Articles/224753/)

 (Or is Cairo already included in the wxWidgets dependancy?  Not sure how
 the wxWidgets variant is working otherwise.)
