license is CC2.5, not DFSG compatible
new texture:

Now, this was another non-power-2 texture.
Original was 160x128. The new one was made at 320x256 and then stretched to 512x256, so will look right when applied to the object correctly.
With this, and the previous applied, it'll make all known-license images compatible. Still have the unknown licenses to fix.
