Lines do not have outlines

[roman-kh]

Outline effect does not affect any lines (based on both Line and Line2).
On the other hand, SelectiveBloom works with lines normally.

I made a sandbox showing the issue.
If you move the mouse over a yellow box or a blue plane they will be outlined.
But the lines are not outline when hovered (the hover does work).

The other problem is that Select ignores the lines too (#134).
But this seems like another issue as outline does not work even the the mesh is passed directly to the effect.
