  11 Beware the Client.transient_for. It can be set to a !NULL value of TRAN_GROUP,
  12 which is not a valid pointer. You must ALWAYS check for TRAN_GROUP before
  13 following transient_for. When TRAN_GROUP is found, Client.group will always
  14 be !NULL. Some smart action should be taken using all members of the group in
  15 this case.

  17 When using coordinates/sizes of windows, make sure you use the right area. The
  18 Client.area rect is the reference point and size of the *CLIENT* window. This
  19 value is not what you see in any shape or form, and gravity is applied to it to
  20 translate it into what you see. The Client.frame.area is the actual position
  21 and size of the entire frame. This is usually the value you want to use, unless
  22 you are in client.c (probably) and adjusting/using the position or size from
  23 the client's perspective.
