// to detect, as the hotspot is defined outside the visible screen (!).
// Presumably, this was done to prevent the cursor from being usable, however
// the only thing that can be done when the wait cursor is shown is to skip
// scenes by left clicking. This bogus hotspot causes the cursor to not be
// drawn at all, thus we detect it and set the hotspot to (0, 0) instead.
// Fixes bug #3487088.
