master turned the gate watch into painted scenery with its own portrait and
result image; Slice 0.9 turns that same hotspot into a real NPC. Kept the
NPC doorway and dropped the result text and image with it -- a hotspot
carries one or the other, never both.
The warden now uses master's `graufurt-gate-watch.png` instead of the raw
copy this branch added: same figure, already optimized. Borin keeps master's
optimized portrait for the same reason.
