I don't mind that because I preprocess the files anyway and anyone who
wants to get a good speed increase should do the same. But it's not a
good idea to turn on/off BFC several times and in some cases, it's nicer
to have the faces reversed. Imagine a file like this:
4 16 1 1 1 1 1 1 1
0 INVERSE
4 16 1 1 1 1 1 1 1
4 16 1 1 1 1 1 1 1
4 16 1 1 1 1 1 1 1
0 INVERSE
4 16 1 1 1 1 1 1 1
It would be nicer to have the quads reversed, this could be done by a
program if a person finds it easier to add 0 INVERSE statements.
