The hit detection code doesn't correctly play well with the skiping of geometries using the renderGeometryFunction. Features/geometries that are not rendered by the replay API are not detected by the hit detection mechanism. For that reason, until we find a solution, we don't use renderGeometryFunction in the vector-layer example.
This commit also removes the click listener, which was used for touch devices. The click listener will be added back when the lib will correctly handle clicks on touch devices.
The new dedicated getfeatureinfo example shows how to combine
feature info from a WMS and a vector layer. The other examples
that previously used getFeatureInfo from vector layers now use
the more appropriate getFeatures.
To avoid surprises for application developers, this change
creates a new getFeatures method. So it is clear now beforehand
whether features or feature info markup is returned. The result
is now also grouped by layer, so application developers always
have a link between a layer and the feature info it returns.
To make getFeatureInfo return markup for vector layers, this
change also adds a featureInfoFunction property to the vector
layer, which gives developers full control over how features are
rendered to feature info markup.
This method is an entry point for getting feature information.
Renderers can use a hit canvas or defer to a layer (source) to
get matching features for a pixel.
For now this is only implemented for vector layers, and it uses
a bbox query because we cannot refine the result because of
missing geometry intersection functions yet.
This is a workaround for our check-example.js PhantomJS script to work with this example. Without this check-example.js fails because xhr.status is 0. I tried to give the explicit file:/// scheme as indicated in https://groups.google.com/d/msg/phantomjs/wFGme0pE-Tk/WUjU5s-27NwJ, but that didn't work for me.
