[plt-scheme] scaling and rotating images using image.ss

Nice to see everyone up so early on a Saturday morning!

Where is 2htdp/universe?  I just installed the latest PLT scheme release,
and I don't see anything called "universe" in the list of teachpacks that
comes up when I try to add a teachpack.

Anyway, I'm glad to see this getting worked on.  I think one of the things
that Scratch got right is that it provides simple image transformations,
which turn out to be very useful in constructing simple-yet-compelling
games.  I think having more of this stuff for drscheme will make it
considerably more compelling for the younguns.
