Have you thought about using squish to replace the existing compression code?

http://www.sjbrown.co.uk/?code=squish

As far as I know it's the best compression code out there, it does not only
produce very good results, but it's also pretty fast. There's an article
about the algorithm here:

http://www.sjbrown.co.uk/?article=dxt

It's a C++ library, but the code is relatively small and self contained. If
you think it's a good idea, I'd be willing to do the integration.

I wasn't aware it existed (apparently it's a much newer project). When I did the library I couldn't really find an open source one (with a suitable license). This one is MIT which would be fine I think. I also wanted to stay away from somewhat standard implementations as it appears to be "IP"-concern ridden enough already. That said, this library looks rather nice, apparently the code is much cleaner. I'm not sure if it's really faster? Quality might be better, though performance is probably more important for use as an online-compressor. It should be pretty easy to convert this library to be suitable for the existing API, there's really not that much interface involved (it needs to be able to handle images smaller than 4x4 however, haven't checked). If it turns out to be better I guess I'd just drop development of my own library (not that I'd have really done much since the first version...).
