Description
  XSetWMName()	performs  a XSetTextProperty() to set the XA_WM_NAME property on the specified window.	XSetWMName() supersedes XStoreName().
  This property can also be set with XSetWMProperties().

  XSetWMName() should be used by the application to communicate a string to the window manager. According to current conventions, this string
  should either:

  o  permit the user to identify one of a number of instances of the same client, or

  o  provide the user with noncritical state information.

  Clients can assume that at least the beginning of this string is visible to the user.

  The  XA_WM_CLASS  property,  on the other hand, has two members which should be used to identify the application's instance and class name,
  for the lookup of resources.	See XSetClassHint() for details.

  For more information, see Volume One, Chapter 12, Interclient Communication.
