+   Modality of _formlayout
+   ~~~~~~~~~~~~~~~~~~~~~~~
+   The `fedit` function and the `FormDialog` class in the private 
+   `matplotlib\backends\qt_editor\_formlayout`
+   gains a new option: `modal`. The current behaviour (modal window) is the default.
+   If modal is set to false, the dialog is shown without returning anything.
+   This allows e.g. using the figures with the options open.
