The Leaflet engine has got a rework to achieve another global performance gain.

When the user generates a document, it is most of the time to display it directly afterwards. Through additional buffers, Leaflet 9.0 is able to create most of the computations needed for display at generation time. This produces a slightly faster generation time, but mainly a much faster first display time. Documents that made use of those new buffers showed a performance gain up to 15%.
