safe::loadTk - Load Tk into a safe interpreter.

       Safe  Tk  is  based on Safe Tcl, which provides a mechanism that allows restricted and mediated access to
       auto-loading and packages for safe interpreters.  Safe Tk adds the ability to configure  the  interpreter
       for safe Tk operations and load Tk into safe interpreters.

       The  safe::loadTk command initializes the required data structures in the named safe interpreter and then
       loads Tk into it.   The  interpreter  must  have  been  created  with  safe::interpCreate  or  have  been
       initialized  with  safe::interpInit.   The  command returns the name of the safe interpreter.  If -use is
       specified, the window identified by the specified system dependent identifier windowId is used to contain
       the “.”  window of the safe interpreter; it  can  be  any  valid  id,  eventually  referencing  a  window
       belonging  to  another application. As a convenience, if the window you plan to use is a Tk Window of the
       application you can use the window name (e.g., “.x.y”) instead of its window  Id  (e.g.,  from  winfoid.x.y).   When  -use  is  not  specified, a new toplevel window is created for the “.”  window of the safe
       interpreter. On X11 if you want the embedded window to use another display than the default one,  specify
       it with -display.  See the SECURITYISSUES section below for implementation details.

       Please read the safe manual page for Tcl to learn about the basic security considerations for Safe Tcl.

       safe::loadTk adds the value of tk_library taken from the parent interpreter to the virtual access path of
       the safe interpreter so that auto-loading will work in the safe interpreter.

       Tk  initialization  is  now safe with respect to not trusting the child's state for startup. safe::loadTk
       registers the child's name so when the Tk initialization (Tk_SafeInit) is called and in  turn  calls  the
       parent's safe::InitTk it will return the desired argv equivalent (-usewindowId, correct -display, etc.)

       When  -use  is not used, the new toplevel created is specially decorated so the user is always aware that
       the user interface presented comes from a potentially unsafe code and can easily delete the corresponding
       interpreter.

       On X11, conflicting -use and -display are likely to generate a fatal X error.
