    work-a-round for tkinter under windows in a virtualenv:
      "TclError: Can't find a usable init.tcl..."
    Known bug, see: https://github.com/pypa/virtualenv/issues/93

    There are "fix tk" file here:

          C:\Python27\Lib\lib-tk\FixTk.py
          C:\Python34\Lib\tkinter\_fix.py

    These modules will be automatic imported by tkinter import.

    The fix set theses environment variables:

        TCL_LIBRARY C:\Python27\tcl\tcl8.5
        TIX_LIBRARY C:\Python27\tcl\tix8.4.3
        TK_LIBRARY C:\Python27\tcl\tk8.5

        TCL_LIBRARY C:\Python34\tcl\tcl8.6
        TIX_LIBRARY C:\Python34\tcl\tix8.4.3
        TK_LIBRARY C:\Python34\tcl\tk8.6

    but only if:

          os.path.exists(os.path.join(sys.prefix,"tcl"))

    And the virtualenv activate script will change the sys.prefix
    to the current env. So we temporary change it back to sys.real_prefix
    and import the fix module.
    If the fix module was imported before, then we reload it.
