I've debugged this further and it seems to be an OpenLayers regression;
https://github.com/openlayers/openlayers/issues/534 has my patch for it.
A workaround would be to call something like `map.moveTo(1,1);` before
adding an instance of my Heatmap layer to initialize the values. I have
http://github.com/hoehrmann/openlayers-heatmap noted that in the README.
