With aircraft that use large PNG textures, mipgen is a *significant*
proportion of the startup t

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 of

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

The 4. Method that I can imagine is to precompute the mipmaps in the loader.
IIRC tests with some of the guys suffering from this problem, providing

If DDS is not politically acceptable, there should be an alternative
way of providing premipped textures.
Mipmap generation is a *significant* portion of the load time,
particularly on the nicer aircraft with large textures.
Even something as simple as a bunch of PNGs concatenated from small to

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

..last time I saw these .dds error messages fly by, the console
wailed about 5 compressed .dds files that needed to be uncompress
