Remix #rainbow #flag with improved palette and #phong #shading with better shadows- - #pride #pbr

u/f8f82804

Correct shadows are implemented with the 0<α factor. To golf this in, I had to drop the diffuse reflection term and reuse constants. Palette improvements just took tweaking without extra characters.
u/f8f82804

Loop restructuring also give a very slight FPS improvement.
