Hmm, not a perfect example. You should call beginEditCP before the
changes, as it might have to create a separate copy of the data for the
aspect. If you do it afterwards it might fail, because you changed te old
version of it.

You can use non-2^n textures if you call setScale(false) on the
TextureChunk. In that case the image will only fill the lower left part of
the next bigger 2^n texture and will not be scaled (which takes forever,
as it uses gluScaleImage). You will have to adjust your texture
coordinates accordingly, or use a TextureMatrixChunk to correct for the
texture only being partially used.
Hope it helps
Dirk
