* If size of the detector is large (e.g. 300x300) dragging of color bar to adjust intensity range leads to very slow update of intensity plot
* It's not clear whether it is due to poor performance of QCustomPlot or our signals are flying too much

One have too
* Study performance of bare QCustomPlot
* Analyze with MacOS Insturments/Performance, where the program spends most of the time
* Revise AwesomePropertyEditor::slotValueChanged, it seems that additional signal blocking is necessary
* Disable activity of HorizontalSlicePlot and VerticalSliePlot: when they are hidden, they should not react on updates in color bar

Optimize also Projections drawing
* Projections update is slow when there is a Simulation running
