[Enhancement]Some form of render layers

[RedRain0o0]

I'm uncertain how exactly this would work, but it'd be some way to have elements render above or below each-other. Example 1: You could have a toony model that has it's eyes under it's bangs, but they render on top. Example 2: You could have another toony model with blocks covering all other parts, but they would render under the other parts, giving it a cel shaded effect
