Aaron Giles, the man responsible for the LucasArts Entertainment Pack, has written an article on his website with an overview of some of the new SCUMM game features.
If you don't remember, the Entertainment Pack was issued by LucasArts in the UK with Windows-friendly versions of Full Throttle, Sam and Max Hit the Road, and The Dig. Aaron, if you didn't know, used to work at LucasArts porting many of the classic games to Macintosh systems and was contacted by the company to update the old games once again.
Some of the lesser known features Aaron points out are full screen mode, graphics smoothing, correct aspect ratio (a welcome feature, I must say), and more. Check out the article for this interesting read. Thanks to bgbennyboy for the heads up!
