Screen position should optionally be per-fragment rather than per-vertex

Original title: "Screen Position Node Broken?"

Original post below:

So I just started experimenting with screen projected textures using the screen pos node, and although it looks ok in SF, it acts really crazy in the editorImage 87

It's not really broken, but it's interpolating per-vertex rather than calculating per-fragment, which will look bad on low-poly objects. There should be a per-fragment option. I'm renaming this thread and switching it to a feature request rather than a bug :)

Edit: There is now a checkbox for per-pixel screen coordinates as of Beta 0.16!

Quick Question: Is the refract shader also interpolated per-vertex? because i'm getting a lot of the similar issues with refraction also:

Yep! Refraction is done in screen space, so it's using the same screen position data as the screen position node :)
