+/// Maps SDL key events to virtual buttons.
+/// Records the state and whether it was pressed/released in the current
+/// iteration.
+/// Multiple buttons can be passed by ORing them bitwise.
+/// The MapKey(SDLKey, Button) function introduces a mapping for the given key
+/// to the given virtual button. Each key can be assigned to one button only,
+/// but there is no limit (well, except for memory, I guess) on how many keys
+/// may map to the same button.
+/// Each iteration should first call ResetInteractiveState() to drop the just
+/// pressed/released information and then pass each SDL_KeyboardEvent to
+/// HandleKeyboardEvent(const SDL_KeyboardEvent &).
+/// The four DEBUG_? buttons do not map to any real SNES/Lufia 2 button and may
+/// be used for debugging or non-gameplay-related input.
