fixed shading same as latest result from prj 8

After fixing UV issues elsewhere the teapot UV now works. Skybox UV still appears incorrect but that may be due to vagueness on how exactly the skybox should be UVed per the assignment. One issue observed is the refractive sphere appears to have incorrectly applied the IOR value.

fixed tile UVs

Debug view showing only the skybox, to try to isolate what issues there are

Fixed sub texture coloring issue, partially fixed mesh UVs. Note that I am UVing spheres with the up/y axis as the latitudinal coordinate, and as the scene is rotated downwards, this is the result.

reflections, refractions are back

skybox, featuring incorrect UV mapping and for some reason its really dark

somethings messed up with the UVing of the model

Fixed tiling, also went ahead and added random offset AA as I already had the ray generation pipeline for soft shadows.

Took some time overhauling the XmlLoader to be more modular, and then had to replace previous Color references with new texture based refs. The plane isnt UVed as expected but otherwise I think my new code is rather eloquent.

UV debug view. Textures soon, fall break has been busy and stressful for me.
