Changed two annoying little problems in musrview (PMusrCanvas):

Browse Source 
(i) It was not always possible to zoom the x-range down below some threshold. The reason was that on overlay histogram frame is needed which is invoked by DrawFrame from the DataTheory Pad. This by default has only 1000 'bins'. If the plotted histogram had more bins (e.g. 16000 bins) zooming was only possible down to the relative ratio (16 for the example). This is fixed now by increasing the 'bins' of the overlay histogram frame.
(ii) When toggling between data view and difference view, the x-range was subtly shrinking.
