Refactor keyframe handling for material diffuse anims. 

The old code was objectively terrible and placed the burden of handling
missing values effectively on the user instead of just figuring it out.
This is objectively better in that we can now count on all values being
"known" at keyframe convert time. Whether that "known" is because it's a
real keyframe, we evaluated it, or we pulled it out of our @$$ is
another story, of course.
