Description
Mapping large polygon datasets in "view" mode sometimes results in broken polygons when zoomed. I think this is due to the default polygon smoothing parameter in Leaflet, which is set to 0.5. In Leaflet, this parameter can be modified, correcting the jagged polygons, by adjusting the default "smoothFactor" parameter in the addPolygons() function.
My question: is it possible to adjust the "smoothFactor" parameter for polygons in Tmap? If not, this would be a great feature to add.

Research direction
Start by tracing tmap's view-mode polygon rendering to the addPolygons() call mentioned in the issue and check how its parameters are exposed. The work is done when users can adjust smoothFactor for polygons and large datasets render without the reported jagged or broken geometry.
