[Overlay] Drawing order of 2D and 3D items and order of overlays in the panel

[dphdave]

As noted at #927

Both 2D and 3D drawing from the overlay lowest down in the Overlays panel appears over 2D and 3D drawing from previous overlays. This does not make sense to me, I would expect all 2D drawing on the screen plane from all overlays to appear over all 3D drawing from all overlays.

2D "3" on the screen plane and 3D red face are drawn by separate overlays. When face rendering overlay is ordered later in the overlay panel, it appears ABOVE the 2D label.

@dphdave - do you have a small snippet to demonstrate?
