I'd like to get the current sampler Texel Size property, in raw shader code we just define the property and unity helpfully fills it in. I can't see how to reproduce this behavior in ShaderForge.
Sorry if it's obvious and I'm just not seeing it.
(Please note, I'm still on v1.28, we can't move to Unity 5.5 yet due to showstopper bugs in some Unity features. )
