- front and back labels where inverted: +z is the front of the cube and -z is its back when looking at the cube from the outside with a camera pointing towards -z (and the cube in front of it). This is the GL definition. - make the synthetic uvXXX debug environment colors match those of the debug environment (except for -Z/back which is magenta instead of black). - add some documentation about skybox and cube map.
