Request: Composition bigger than 4096px

[dRead]

Sweet! I can't wait for R4 just for the larger comp size. I did a club install out here that is a 6 wide, having to accept 3840x480 is ok but could be way better, so stoked.

Might be worth (perhaps already implemented in 4) having a way to indicate that a file is too large. I was initially confused after trying to load some large images to scroll.
