+  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)
