Altough s3tc is quite widespread, since we are using 2^n sided textures, it should be trivial to add support to down-size sides by 2^n if the user wishes so, at the expense of longer loading time. We could also provide a way to convert the actual files. Models could also be LODed during

Technically, the extensions can be queried in run-time (and there are a few more that can be included easily). I don't see any reason why would anyone with compatible HW want to disable this, but who knows? Perhaps some purist dislikes that s3tc is lossy ;) The other problem is that this is
