doesn't need to do this on the fly. OpenGL requires that texture dimensions
be a power of 2 (32, 64, 128, 256, 512, 1024, 2048, etc.) so if we feed in
something else, OSG will rescale it on the fly before registering it as an
OpenGL texture.
They are not perfect as the Equipement is not good enough, but though they works quite good!
