No. Not a "non-programmer".  Since a shader consists in taking some
input (point position, normal,...), applying some algorithm, and
returning some final value, it's programming.

However, that's someting a beginner prorammer (someone who already
have the aptitude to create a #macro) should be able to do without
learning C++ first.

IMO, ideally, the shading language should be part, or a subset, of
SDL.
