matplotlibwidget.py -> MatplotlibWidget creates figure without figure manager

[GoogleCodeExporter]

It's not possible to set the axis instance of the matplotlib widget
as current pyplot axis (pyplot.sca()). It will raise an Exception
instead saying "Axis instance was not found in a figure"
So, as I was told, this is, because the Figure() is created not via pyplot, 
without using a figure manager.
