Heatmap PNG's don't resize with zoom

[bozdoz]

On the Leaflet demo: http://sunng87.github.com/heatcanvas/leaflet.html

If you zoom in or out, the map data seems incorrect, because the PNGs cover more or less area. For example: at the initial zoom level, central-west America has no data, once zoomed out the data seems to span all of America, and zoomed in, it seems empty again.

There should be a way to resize the PNG appropriately once the map zoom level has changed.

Yes, this is designed feature. The leaflet plugin only calculates and shows heat map in current view. So when you zoom in and out, it redraws based in new extent.

I am thinking about adding an option to control this behavior: to redraw based in global or local.
