I wasn't sure how to fix this. First step is to refactor the panning
controls out of the GTK HID's common code, and make it renderer
specific. I have a patch or two somewhere which starts that.

I guess one could project the major axes if the board layout area in
screen space, then determine which screen-space axis (and sign thereof)
most closely matches each direction.

Alternatively, we could just make the pan controls work on the 3D view
space, not in board space.

We could even disable panning by the scroll-bars entirely when in 3D
view mode. (How many 3D cad programs have you seen with panning
scroll-bars? - My total is zero).
