* or winPtr->changes.y has changed (otherwise a size change can
|
||
* spoof us into thinking that the position changed too and defeat

* geometry requests coming from inside the window hierarchy. If
|

* we accidentally interpret a response to our request as a
|
||
* user-initiated action, the window will stop responding to
|
||
* new geometry requests. To make this distinction, (a) this
|
||
* procedure sets a flag for TopLevelEventProc to indicate that
|
||
* we're waiting to sync with the wm, and (b) all changes to
|
||
* the size of a top-level window are followed by calls to this
|
||
* procedure.
|
||
* 2. Races and confusion can come about if there are multiple
|
||
* operations outstanding at a time (e.g. two different resizes
|
||
* of the top-level window: it's hard to tell which of the
|
||
* ConfigureNotify events coming back is for which request).
|
||
* While waiting, all events covered by StructureNotifyMask are
