Printing 'square' data comes out rectangular

[Anders-Markvardsen]

1. Load the attached nenux file
2. Do a colour contour plot which plot data as square
3. Chose File->Print which print data as array

This is important e.g. for the SANS guys who has users that
prints out data and then uses a ruler to identify features.

Initial task is to see if there is some way to trick MantidPlot
into doing this. In this context investigate if MantidPlot has
a feature supporting this but this feature is not working.

Estimate is one man day
