This MR mainly changes the widget used to display the scatter plot in the intensity view:
- It replaces the animated toolbar with a toolbar on the top
- It adds a colorbar
- It adds a menu to change scatter symbols and symbol size
It solves the following issues:
- closes #12 (closed): Use same colormap in IntensityView
- closes #20 (closed): Use plot data margins so scatter and curves do not 'touch' the plot edges
- closes #21 (closed): IntensityView: Bottom part takes a lot of space when first shown
- related to #16
