Used by the routine at RENDER_DYNAMIC_OBJECTS.

Called every turn by RENDER_DYNAMIC_OBJECTS; it acts only when PANEL_DUE is set, as TAKE_OR_LEAVE sets it when what he carries changes. The main loop comes in at SHOW_CARRIED_NOW on entering a room, to draw them regardless.

The panel shows three of the four carried entries, CARRIED_SHOWN's two and CARRIED_LAST (four bytes each: the graphic first), in three boxes 24 pixels square along the bottom of the screen, at pixel x 16, 40 and 64. For each, the box is cleared in the screen buffer, the thing's sprite drawn there through the spare record at PANEL_RECORD (DRAW_SPRITE in DRAW_OBJECT, with no projection, and no flip bits so the sprite is turned back to face its stored way), and the box copied to the screen (BLIT_TO_SCREEN); then its three by three attribute cells are coloured by the graphic's low three bits, from CARRIED_COLOURS. An empty entry is cleared, and coloured as if graphic 0.
