Their FAQ states that "[we] don't have to obtain a license of the S3TC
patent to use any of NVIDIA's products" but
it also adds that "certain uses of NVIDIA Texture Tools source code
cannot be considered NVIDIA products
anymore." Thus, forking the project and integrating it into Wine would
probably have the same legal status as
writing an own S3TC (de)compressor within Wine.
Seems like asking for a license or directly using the binaries of this
lib are the only options we have then. Forking NVIDIA TT and disable it
by default would probably not be accepted by AJ I guess...
