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 project is open. At least as an option. For small data or smaller search radius the live behaviour would still work well, but for larger data sets of larger search radius, such a cache raster would speed things up significantly, especially in a server scenario.

Would such a cache be technically possible and useful?
