Patch to fix issue with a plot window not having updated calibration values set

If a macro draws a new plot using Plot.create() in an existing plot window by
calling Plot.update(), a subsequent usage of toScaled for that plot will give
the wrong values. toScaled will scale its arguments using the properties of
the plot drawn when initially creating the plot window. This happens
completely without the user being aware.

The reason for this as far as I can tell is that using the Plot.update() macro
function calls the drawPlot() method of the plot window PlotWindow instance.
But this does not transfer the calibration data from the Plot to the
ImageProcessor of the PlotWindow instance. A patch that fixes this issue for
me is attached.
