How about:

Window Movement
===============

Window manager implementors should refer to the ICCCM for definitive
specifications of how to handle MapRequest and ConfigureNotify events.
However, since these aspects of the ICCCM are easily misread, this
document offers the following clarifications:

 - Window managers MUST honour the win_gravity field of WM_NORMAL_HINTS
   for both MapRequest _and_ ConfigureNotify events [1]

 - Applications are free to change their win_gravity setting at any time

 - When generating synthetic ConfigureNotify events, the position given
   MUST be the top-left corner of the client window in relation to the
   origin of the root window (i.e., ignoring win_gravity) [2]

[1] ICCCM Version 2.0, §4.1.2.3 and §4.1.5
[2] ICCCM Version 2.0, §4.2.3


These are the things I was confused about, anyway; does anything else
need to be added?

Agreed.
