I'd forgotten about the attributes... <Doh! Airhead!!>

OK, that means I can at least solve part of the problem. Cheers.

Oohhhhh - and I guess if those dimensions don't equal what I asked for
I can figure that either a) we're in software and the screen doesn't
go that big or b) we're in hardware.

{ I mean, technically, this is only going to work in hardware modes,
but if I ever do release it, SOMEONE, SOMEWHERE will try it in
software and it'd be nice if it was at least graceful if not actually
fast.. }

people's floors in the comfort of my own bed [1] and, in extremis, while
driving.. and hence only have software rendering. ]
