-- TextBox drew its box border and glyphs through Font.drawBox/drawCode
-- with a flat setColor, never touching GbcPalette, so dialogue text never
-- picked up a COLORS palette even though every other Chrome.lua-based
-- screen did.
--
-- No real shader runs headless, so this asserts on which seam gets called
-- rather than checking a rendered pixel; tests/drivers/gold_menu_shots.lua
-- is where a real box gets checked by eye.
