WS30: Fix filtering of texture atlas

Browse Source 
Previously we were taking the nearest pixel from the nearest
mipmap.  Which was braindead.  Now just use the OSG defaults,
which are NEAREST_MIPMAP_LINEAR for MIN and LINEAR for MAX.

Thanks to Julian and Henning for helping diagnose this on
the weekly hangout.
