cube example: Switch to a power-of-two texture

Just to make sure it runs with strict WebGL 1 implementations.

This cannot generally be a solution, naturally, so requiring
WebGL 2 is more likely the way to go, but in the case of this
example it seems the only thing we need is to resize the image
file, so we might just as well do that.
