[Scummvm-cvs-logs] CVS: scummvm/common system.h,1.42,1.43

[Max Horn]

Update of /cvsroot/scummvm/scummvm/common
In directory sc8-pr-cvs1:/tmp/cvs-serv22592

Modified Files:
	system.h 
Log Message:
added explicit virtual destructor; added API which makes it potentially possible to have an overlay with a different size than than the 'normal' screen (e.g. if the game runs at 320x200 and a 2x scaler runs, the overlay could be made 640x400 big, if the backend supports that)
