DramaticShapeVoxelMod/tests/bills_desk_shots.lua

-- Scratch driver: shots of Bill's desk, for the `bills_desk`
-- voxelization.  The desk fills cells (1,4) and (2,4) of Bill's house
-- with its chair in the walkable cell (1,5) below it, so these are the
-- angles you can actually stand at: head-on from the floor two cells
-- south, and from either flank.
