Ok, I do understand now. In my career, I have not met a 800x600 projector - but the problem scales (pun intended^^), of course.
Would you be willing to share your hacky mess or make a PR? I really do get what you're referring to now and do think that if you won't contribute, I'll have to write my own hacky mess(;
Older projectors have this resolution, but 1024x768 is more common. Some of the projectors at my university are 800x600 and I've run into them at conferences where the hotel conference facilities are older and haven't kept up.
