Ah.. tab key (and other view modifiers) might produce some confusing
results! The GL rendering code is pretty ignorant of them at the moment
unfortunately.

Ah - yes, I didn't extend the walls down to the back-side pads. I guess
this was a mistake on my part.

The difficulty is that the layer stack is something which is quite hard
to define. 3D Rendering of board which have the "solder" side as layer
2, then proceed with inner layers on 3, 4.. are a problem!

When we get the ability to keep layer colours in the PCB file, this
should be easily solved by allowing the user to re-order their layers
(for example).

Best wishes,
