This did look kind of awful...

I agree with Syd, this is the best option.  You should not have to pull 
it in, however, I am pretty sure the SID folks already added it to the 
cygnus tree.  You just need to include it in the insight module, and 
fiddle with dependencies.

This seems like a waste of time.  There aren't any other good C-based 
ones
out there, and a quick glance at the BLT code will convince you this is 
not altogether trivial.

And you really don't want to use one of the canvas based ones,
those get too slow too quickly.

George uses cygwin to build BLT himself - or at least he did last time I 
talked to him.  I would be really surprised if he has switched to Visual 
Studio.  So I don't think this should be much of a problem - just make 
sure the version you have is up to date.

If you do run into any snags, you should surely contact George, he is 
usually very helpful about things like this.

Go with BLT!
