9962: Draw a sprite, choosing the routine from the drawing mode
Used by the routine at DOOR.
Neither this nor DRAW_SPRITE_COLOURS does any drawing. Each loads the address of its own table of eight routines and falls into the tail of DISPATCH_ACTOR, which indexes the table and jumps through the JP (HL) the tape left at $5CB0 -- the same machinery that picks an actor's handler, reused for picking how a sprite gets put on the screen.
The mode is the top three bits of the actor's +$05, so the low five bits are free for other flags -- PLAYER_AT_DOOR reads bit 6 of the same byte as a door's facing.
