Plate icons: keep them inside the gap to the next plate

Browse Source 
The plate's icons, number and name scale with the plate's depth, but they sit in
the gap to the next plate, which scales with its width. On a long, narrow bed
(a 95 x 500 mm belt) they came out 40 mm wide and ran across the neighbouring
plate. The scale is now also bounded by the gap, which leaves ordinary beds
unchanged.
