Provide a zoom to fit the diagram content strategy for sparsely populated diagrams

[NiklasRentzCAU]

This is related to KIPRA-1895.

The current zoom to fit behavior aligns the viewport with the size of the current diagram clip node, which might be much larger (or even smaller) than the bounding box of the actual (nested) diagram content.

This may be given in particular if the diagram clip node's (potentially large amount of) ports is turned invisible.

A dedicated zooming strategy ZOOM_TO_FIT_CONTENT would be beneficial than.

That's true and might be as this feature never released before v1.0.0.
We could add pointers to the corresponding changes here and close I think.

Fixed since this commit, closing.
