Reverted the update to the QWT 6.1 code to make QwtPlot::canvas() return a QwtPlotCanvas -- it now returns QWidget. This means our local copy of Qwt is the same as the published version so we should be able to stop maintaining our own copy when Uwe pushes the multiaxis stuff with 6.2. Also fixed the LTM tooltip - the zoomer has been removed.
