Zoom out from peak in report

[Owen Arnold]

A problem with #8428 is that it's not possible to zoom slightly out from a peak. This would be very useful when you want to visually check the edge-of-detector condition, which has been the cause of problems lately.

Would also be good to set the viewing axis. We should do this at the same time. Currently the projection X, Y is always for the first two dimensions. We should just need to expose these options on the PeakReport interface.

FakeMDEventData(InputWorkspace=qLab, PeakParams=[1000, 1, 1, 1, 1])

SetSpecialCoordinates(qLab, 'Q (lab frame)')

pathToInstrument = os.path.join(config["instrumentDefinition.directory"], 'CRISP_Definition.xml') # Note that the instrument doesn't matter. Choose a small one.
instWS = LoadEmptyInstrument(Filename=pathToInstrument) # Only do this so that we can provide the parameter to CreatePeaksWorkspace
pw = CreatePeaksWorkspace(InstrumentWorkspace=instWS, NumberOfPeaks=1)

peak = pw.getPeak(0)
peak.setQLabFrame(V3D(1, 1, 1), 1)

peaks_qLab_Integrated = IntegratePeaksMD(InputWorkspace=qLab, PeaksWorkspace=pw, PeakRadius=0.2, BackgroundInnerRadius=0.3, BackgroundOuterRadius=0.4)

refs #8561. Add new options.

This should be working now. The self-contained script above should demonstrate the zooming in and out working, as well as the ability to switch the x-y axis projected.

using pips install PIL and reportlab first. You may want to set up a virtual environment for these.

Not sure how this is different from the zoom out that already works in the View menu, but the script does work for me. Are you adding dependencies to mantid since I had to install python-imaging and python-reportlab?
