getDataExtent only works against the features currently in the layer --
it isn'at aware of the 'subfeatures' inside the clusters.
I use this instead:
var e = m.layers[0].features[0].geometry.getBounds();
for (var i = 0; i < m.layers[0].features.length; i++) {
for (var j = 0; j< m.layers[0].features[i].cluster.length; j++) {
e.extend(m.layers[0].features[i].cluster[j].geometry.getBounds());
}
}
This creates an extent that takes into account all the features.
