Zoom level threshold where MapboxMap will automatically switch projection from MapProjection.Mercator to MapProjection.Globe or vice-versa if MapProjectionDelegate.setMapProjection was configured to use MapProjection.Globe.
If MapboxMap is using MapProjection.Globe and current map zoom level is >= TRANSITION_ZOOM_LEVEL - map will use MapProjection.Mercator and MapProjectionDelegate.getMapProjection will return MapProjection.Mercator.
If MapboxMap is using MapProjection.Globe and current map zoom level is < TRANSITION_ZOOM_LEVEL - map will use MapProjection.Globe and MapProjectionDelegate.getMapProjection will return MapProjection.Globe.
If MapboxMap is using MapProjection.Mercator - map will use MapProjection.Mercator for any zoom level and MapProjectionDelegate.getMapProjection will return MapProjection.Mercator.
