Khronos's Conformance Test Suite (is it abandoned?) needs attention (lighting normals)

Here is a problem in the CTS that needs addressing.
https://www.khronos.org/bugzilla/show_bug.cgi?id=1950
https://github.com/KhronosGroup/COLLADA-CTS/issues/15

(Basically many or all of the cube shape examples need lighting normal added to their files to match the Blessed images. Maybe there is a way to run all of the examples through a normal computing/adding conditioner.)

Start by reading the linked Khronos Bugzilla report and COLLADA-CTS issue, then inspect the cube shape examples and their Blessed images in the CTS. Determine which examples lack lighting normals and whether the proposed normal-computing conditioner is feasible; done means the affected examples include the required normals and match the Blessed images.
