[map-basic] Mouse zooming does not work properly after migration to vuelayers 0.12.0-rc.21

[lubojr]

With migration to Openlayers 6 + Vuelayers 0.12.x allowing non-integer zoom levels, our zooming stopped working properly (zooming happens in very low increments). I have so far been able to investigate following: Concerned component is https://openlayers.org/en/latest/apidoc/module-ol_interaction_MouseWheelZoom-MouseWheelZoom.html

When passing non-default useAnchor parameter as false and constraining zoom levels via constrainResolution - either on view or on MouseWheelZoom control (which yield nicer looking and crisp vector tiles anyway), it works fine and is merged now to main. The problem is that anchor of zooming is set to center of page, which is a relict of past and does not bring a nice user experience.

The improvement would be to investigate and solve why the zooming does not work properly without useAnchor=false

Most likely connected to issue ghettovoice/vuelayers#413.

Reverted the vuelayers package version to 0.12.0-rc.20 for now and removed the MouseWheelZoom hack, let's hope for a fix soon on vuelayers' side :-)
