That's good and I'll definitely try Chrome. But, wouldn't it be great if the library/framework just took care of that? In fact, one of the frameworks -- Shining -- referred from the other post has a JavaScript plug-in that seems to do the resizing for different resolutions (although it's implemented in the ugliest way possible, IMO).
Scaling a presentation is not an edge case -- as other commenters have mentioned, working with undesirable screen resolutions is the default for presenters. It would be better to have the presentation scale automatically to the window size than to have to press Ctrl+/Ctrl- to try to get it reasonably close.
