* has already been scheduled for this window; no
* need to schedule another one.
* WM_NEGATIVE_X - non-zero means x-coordinate is measured in
* pixels from right edge of screen, rather than
* from left edge.
* WM_NEGATIVE_Y - non-zero means y-coordinate is measured in
* pixels up from bottom of screen, rather than
* down from top.
* WM_UPDATE_SIZE_HINTS - non-zero means that new size hints need to be
* propagated to window manager.
* WM_SYNC_PENDING - set to non-zero while waiting for the window
* manager to respond to some state change.
* WM_VROOT_OFFSET_STALE - non-zero means that (x,y) offset information
* about the virtual root window is stale and
* 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
* allow the user to change the height of the
* window (controlled by "wm resizable" command).
