prroblems with details displayed in hover over

[cfsnook]

James 10/12/15: The hover over text doesn’t resize/relocate with respect to the diagram (i.e. zoom in, zoom out doesn’t change hover over text size or position); note I am using GTK2, not GTK3 so this may not be an issue in GTK3 (I am working on getting the relevant C library installed to use GTK3).

Colin - At the moment it is just positionsed at a fixed offset from the target element. It should be possible to find the co-ordinates relative to the boundary of the canvas and deduce the best position from this. However, using the 'tool-tip' hover over text for this feature is not ideal anyway. Another problem is that the text often gets in the way. Consider re-implementing this in a better way. (E.g. using a separate view which refocusses depending on hover)
