* need to schedule another one.

* down from top.

* propagated to window manager.

* manager to respond to some state change.

* needs to be fetched fresh from the X server.
|

* WM_ABOUT_TO_MAP - non-zero means that the window is about to be

||||
* mapped by TkWmMapWindow. This is used by
|
||||
* UpdateGeometryInfo to modify its behavior.

||||
* WM_MOVE_PENDING - non-zero means the application has requested a

||||
* new position for the window, but it hasn't
|
||||
* been reflected through the window manager yet.

||||
* WM_COLORMAPS_EXPLICIT - non-zero means the colormap windows were set
|
||||
* explicitly via "wm colormapwindows".
|
||||
* WM_ADDED_TOPLEVEL_COLORMAP - non-zero means that when "wm colormapwindows"
|
||||
* was called the top-level itself wasn't
|
||||
* specified, so we added it implicitly at the
|
||||
* end of the list.
|

* WM_WIDTH_NOT_RESIZABLE - non-zero means that we're not supposed to
|
||||
* allow the user to change the width of the
|
||||
* window (controlled by "wm resizable" command).
|
||||
* WM_HEIGHT_NOT_RESIZABLE - non-zero means that we're not supposed to
