Ah, okay then. Speaking of BPTC - what is its patent situation? From a quick glance at the extension spec, it does seem to use S3TC's interpolation method, so it likely is not safe from S3's patents. But I may be wrong there, as BPTC is quite messy and convoluted, and I may have misinterpreted that interpolation value sequence.
