Is there any way, in Gem, to draw arbitrary curves ([curve3d], [surface3d]) with color gradients?

I guess, worst-case bad workaround would be to algorithmically generate a pix_texture (but Gem's support for this isn't marvelous either).

Or write a shader (yikes, that's gonna eat up hours that I don't have).

Would be nice if you could write per-control-point colors into the curve.
