-- The slot machine's menus sit where the original draws them (#1811).
--
-- The bet menu is `hlcoord 14,11 / b=5 / c=4 / TextBoxBorder`
-- (engine/slots/slot_machine.asm:83-86), i.e. a 6x7 box whose bottom edge is
-- the last row of the screen, with the multipliers at hlcoord 16,12 and the
-- cursor at wTopMenuItemX 15 (asm:77-78, :87).  "One more go?" is a
-- TWO_OPTION_MENU at hlcoord 14,12 (asm:136-138) over the YES_NO_MENU body
-- (width 4, height 3 -> a 6x5 box; data/yes_no_menu_strings.asm:10).
-- The "Want to play?" prompt is not this screen's at all: PromptUserToPlaySlots
-- asks it before LoadSlotMachineTiles (asm:9-23), so the screen opens on the
-- bet menu.
