  44
  45 /*  FUNCTION
  46         Activates the specified window. The window gets the focus
  47         and all further input is sent to that window. If the window
  48         requested it, it will get a IDCMP_ACTIVEWINDOW message.
  49
  50     INPUTS
  51         window - The window to activate
  52
  53     RESULT
  54         None.
  55
  56     NOTES
  57         If the user has an autopointer tool (sunmouse), the call will
  58         succeed, but the tool will deactivate the window right after
  59         this function has activated it. It is not a good idea to try to
  60         prevent this by waiting for IDCMP_INACTIVEWINDOW and activating
  61         the window again since that will produce an annoying flicker and
  62         it will slow down the computer a lot.
