[PATCH weston] Popup stacking

[Emilio Pozuelo Monfort]

Hi,

These two patches fix bug #74831 in two different ways. One of them,
originally written by Philip, positions the popup on top of all other
surfaces in the layer. That means that you can still end up with the
parent surface behind a second parent (as the comment in the commit
explains).

The other commit activates a surface when you right-click on it. That
is what at least gnome-shell does (I don't know about other WMs) and
we may want to do the same. That change fixes the pop positioning bug
because the parent surface is going to be on top, so placing the popup
just above the parent surface is enough to have it on top of everything
else.

I'm leaning towards the second approach (activating the surface upon right
click). Thoughts?

Emilio
