May I ask what the purpose of the arbitrary uv texture lookup is? What functionality does this provide?

@sharktacos This is needed to correctly handle yarnsizes which are controlled with a texturemap.
The shader needs to be able to look up the yarnsize of the neighbouring yarns in order to handle the varying yarnsizes correctly, that is, read the texture at uv coordinates that are not the current sampling point.
