+.SH DESCRIPTION
+.PP
+These procedures are analogous to the X library procedures
+with similar names, such as \fBXConfigureWindow\fR. Each
+one of the above procedures calls the corresponding X procedure
+and also saves the configuration information in Tk's local
+structure for the window. This allows the information to
+be retrieved quickly by the application (using macros such
+as \fBTk_X\fR and \fBTk_Height\fR) without having to contact
+the X server. In addition, if no X window has actually been
+created for \fItkwin\fR yet, these procedures do not issue
+X operations or cause event handlers to be invoked; they save
+the information in Tk's local
+structure for the window; when the window is created later,
+the saved information will be used to configure the window.
+.PP
+See the X library documentation for details on what these
+procedures do and how they use their arguments.
+.PP
+In the procedures \fBTk_ConfigureWindow\fR, \fBTk_MoveWindow\fR,
+\fBTk_ResizeWindow\fR, \fBTk_MoveResizeWindow\fR, and
+\fBTk_SetWindowBorderWidth\fR,
+if \fItkwin\fR is an internal window then event handlers interested
+in configure events are invoked immediately, before the procedure
+returns. If \fItkwin\fR is a top-level window
+then the event handlers will be invoked later, after X has seen
+the request and returned an event for it.
+.PP
+Applications using Tk should never call procedures like
+\fBXConfigureWindow\fR directly; they should always use the
+corresponding Tk procedures.
+.PP
+The size and location of a window should only be modified by the
+appropriate geometry manager for that window and never by a window
+itself (but see \fBTk_MoveToplevelWindow\fR for moving a top-level
+window).
+.PP
+You may not use \fBTk_ConfigureWindow\fR to change the
+stacking order of a window (\fIvalueMask\fR may not contain the
+\fBCWSibling\fR or \fBCWStackMode\fR bits).
+To change the stacking order, use the procedure \fBTk_RestackWindow\fR.
+.PP
+The procedure \fBTk_SetWindowColormap\fR will automatically add
+\fItkwin\fR to the \fBTK_COLORMAP_WINDOWS\fR property of its
+nearest top-level ancestor if the new colormap is different from
+that of \fItkwin\fR's parent and \fItkwin\fR isn't already in
+the \fBTK_COLORMAP_WINDOWS\fR property.
+
+.SH BUGS
+.PP
+\fBTk_SetWindowBackgroundPixmap\fR and \fBTk_SetWindowBorderPixmap\fR
+differ slightly from their Xlib counterparts in that the \fIpixmap\fR
+argument may not necessarily be deleted immediately after calling
+one of these procedures. This is because \fItkwin\fR's window
+may not exist yet at the time of the call, in which case \fIpixmap\fR
+is merely saved and used later when \fItkwin\fR's window is actually
+created. If you wish to delete \fIpixmap\fR, then call
+\fBTk_MakeWindowExist\fR first to be sure that \fItkwin\fR's window exists
+and \fIpixmap\fR has been passed to the X server.
+.PP
+A similar problem occurs for the \fIcursor\fR argument passed to
+\fBTk_DefineCursor\fR. The solution is the same as for pixmaps above:
+call \fBTk_MakeWindowExist\fR before freeing the cursor.
