Go ahead and fix it :-)

--as-shown determines whether you use the layer stack as shown, or the
layer stack as defined by the pcb.  It's a "what's on top" setup.

Because it's defined *in* lesstif and gtk, so they expect you'll only
call that for the gui.  It won't do what you want now.

I object to adding things "for this particular case" without
considering future expansion or flexibility.  Adding something that
selects a top side, without considering arbitrary rotation and/or 3-D
view, is shortsighted.

ShowSolderSide is special because it determines which smt pads are
drawn at which times, and which mask is drawn.  It doesn't control the
orientation of the board at all; that's done in the HID.

The core needs to know the stackup, but it doesn't need to know the
orientation.
