Hi,
I tried the new heatmap renderer in QGIS master. It works nicely.
I wonder if we could introduce a caching mechanism in a temporary raster
layer to speed up zooming and panning? The idea would be to recreate the
heatmap every time the project is loaded and then cache it while the

Hmm, handling a cache for the heatmap renderer would probably be quite
challenging. Let's say a temporary raster heatmap is created to ease
panning, you'd have to re do this every time the zoom level is changed. You
could decide to cache as many temporary raster hearmaps as zoom levels
