WebGLRenderTarget and setViewport and setScissor

[bunnybones1]

I'm having trouble with setViewport and setScissor when I try to use it with WebGLRenderTarget.
Here's an example:

I've gone through three.js to the best of my abilities, and feel like it could actually be a webGL bug, but I'm just not sure.
The quick workaround to make setViewport and setScissor work is to call the offending render twice.

I've figured it out. I need to run setRenderTarget before running setViewport, which I guess operates on the last bound renderTarget.
