Oh, I forgot in the previous mail:
There is a 5. Solution:
Provide premipmapped uncompressed dds files and compress them with something
like gzip. Osg can

But that means we could at the point where the warning happens compute
the mipmap levels on the cpu in the loader thread. osg::gluScaleImage
could be used to do this I think (or something similar not requireing
a context). This one is an imported version

This should be fixed too, as of now, in GIT.

Many thanks for working toward a proper solution,
