Can see 'Out of SVM stack space.' messages on the console.

@Brecht Van Lommel (brecht), leaving this one to you.

That mouth.uvswitch.c node group is kind of crazy and crosses a limitation of our shading system, which exists because of GPU rendering limitations. We should fix the crash but I'm not sure how easy it will be to make this setup actually work.

There must be a simpler way to create this setup with much fewer nodes, and automatically adapting to a given number of tiles in some image?

Thanks Brecht, Now I know is because of the limit, I will try to simplified it.
But it would be good if there is a warning.
