I'm experimenting with an effect that uses the stencil buffer. I'd like to be able to share the depth/stencil render buffer between different targets.

It seems like i've been able to do what i want by changing this:

to:

setupRenderBufferStorage( renderTarget.ownDepthBuffer || renderTargetProperties.__webglDepthbuffer, renderTarget )

and creating the buffer myself on the render target.

I am unable to find a way to do this without modifying the library. The super private caching internals seem to be in the way, since createRenderbuffer() is both called and stored inside the renderer.

I don't understand what exactly depthTexture is, but it seems like it is something similar to this, and can be provided from outside. Is there a way to achieve what i'm doing here without the hack?
