What specificly does this patent cover and what parts of WINE would it affect? (i.e. which bits of windows, if implemented in WINE, would fall under the patent?)
Probably not much, since (IANAL) it'd be the GL driver doing the actual work. That's why NVIDIA's have it, but Mesa or the open-source ATI doesn't.
The big problem with this patent is that, well, nobody really knows much about what exactly is allowed or what is not (and this causes also some problem to the DRI people).
Anyway, in the Wine code, if the GL driver supports compressed texture via S3TC, then Wine will not violate any patent by just passing the data from the application to the driver.
The big question is when the card does not support it and we need to do the decompression in software and send it back to the card.... In this case, do we violate it or not ?
