The config dialog of each annotation tool is now a single grid layout without group boxes. Everything is aligned.
Things to discuss:
- Arrangement of "Shape fill" checkbox and color picker in Geometrical shape and Polygon
- Inline note: right part is auto expanding. How to avoid this?
- Preview of popup icon is ok on the right of the combobox for me. Stamp preview needs a separate work, because it is too small.
- Method `createStyleWidget` may be renamed at this point given that it does not create a widget
