R=me, with one comment nit.

That's a way better name.  If you know you're using LCD text then you also know that the layer can't have a transform that's anything other than an integer translation, so therefore doesn't need border texels.  Therefore, I'd argue that it encapsulates both.

If false, I think we draw the background color of that layer?

Ah yes, I was mistaken.
