+NAME
+    XCreateInsensitivePixmap - create a grayed-out copy of a pixmap
+
+SYNOPSIS
+    Pixmap XCreateInsensitivePixmap( Display *display, Pixmap pixmap )
+
+DESCRIPTION
+    This function creates a grayed-out copy of the argument pixmap, suitable
+    for use as a XmLabel's XmNlabelInsensitivePixmap resource.
+
+RETURN VALUES
+    The return value is the new Pixmap id or zero on error.  Errors include
+    a NULL display argument or an invalid Pixmap argument.
+
+ERRORS
+    If one of the XLib functions fail, it will produce a X error.  The
+    default X error handler prints a diagnostic and calls exit().
+
+SEE ALSO
+    XCopyArea(3), XCreateBitmapFromData(3), XCreateGC(3), XCreatePixmap(3),
+    XFillRectangle(3), exit(2)
