I do not think that the comment:  "A window is requested to become a normal
state" is a useful. Can you remove the sentence. (I think the second sentence is
still useful)

Can you also remove the comments for MAXIMIZE, MINIMIZE, FULLSCREEN, SNAP_LEFT,
SNAP_RIGHT events too (Keep the TODO)?

Removed individual comments, and added the overview of these events.
