A warning about "Unsupported texture" is caused by irrlicht internally.

To get a warning-free release, this particular message is now only
printed in debug mode (and a line is added that this message will
not be printed in release mode). Just a dirty work around, we can't
change this and have to wait for irrlicht to get fixed.
