Why not use an input port or two and use the provided Rendering
Destination Dimensions patch?

I use the formula
Pixels = Units x Rendering Destination Pixels Wide / 2
Yeah, I knew that part but my question was really how to get
"Rendering Destination Pixels Wide" in a plugin.
It looks like glGetIntegerv(GL_VIEWPORT) seems to work so I'll use
that but just thought there might be a more obvious way. Most of the
3rd party plugins I've looked at just use pixel dimensions for input,
probably because there wasn't an obvious way to get the rendering
destination in pixels.
