Used by the routine at NEW_GAME.

Called every turn by NEW_GAME. The view shows the knight's cell and the eight round it; they are drawn back to front, the back ones in an order that depends on which of them are built on. Everything here is in the view's coordinates: with the town turned round (VIEW) his cell is turned round first (TURN_CELL), and the map is read through the view (LOOK_UP_CELL), so U-1 is always further back.

Five cells lie behind or beside his: U-1 V+1, U-1, V+1, U-1 V-1 and U+1 V+1. A bit for each that is not open ground, bits 0 to 4 in that order, picks one of 32 records of five steps in DRAW_ORDER. Each step byte gives a cell as an offset from his -- bits 4-5 for U, bits 6-7 for V: bit 5 (or 7) the same, bit 4 (or 6) one more, neither one less -- and in bits 0-1 what to draw there: 0 the things in it (LIST_THINGS_IN_CELL, SORT_AND_DRAW_THINGS), 1 its walls (DRAW_WALLS), 2 its walls by DRAW_OUTLINE, 3 nothing.

Every record gives the five cells, each with action 1 if it is built on and 0 if not: actions 2 and 3 are in no record, and their instructions never ran. Last come his own cell and the three in front of it, V-1, U+1 and U+1 V-1, each with its walls by DRAW_OUTLINE -- the routine action 2 would have used -- and then the things in it.
