XW_CROSSING_LEFT and XW_CROSSING_ENTERED mean the same as they do on X,
so those two should be obvious to anyone with reason to look at the
xwidgets code.

XW_CROSSING_NONE is sent on a MotionNotify or an XI_Motion event, where
no crossing took place, so I think that's self-explanatory as well.

But if you still insist, I have no objections to installing a comment
explaining things there.
