TSL ColorNode/FragNode issues

[DennisSmolek]

There are two issues I'm reporting, one came up in the discord while putting together the other so I figured I'd tie them together.

1. When dumping positionLocal to a colorNode field the output is expected. However if you put it in the fragmentNode it corrups and goes weird. Making it scary if we can use it as an input in further down-thread parts of the shader.

Left: Weird, Right: Expected

In my test I'm making the materials outside react and also as `NodeMaterial`s instead of `MeshStandard` however this is after testing all sorts of combos including standard ``

UPDATE: My second issue turns out to be in the vanilla version too. I'll move that portion over to three.
