Please write blog posts, create tutorials, or develop workshops that show off cool ways to develop applications that use OL3. The examples should be kept very simple. This download functionality is neat, but it's really a gratuitous use of non-map related functionality. While it does demonstrate the use of `format.writeFeatures()`, this is buried in too much additional code that is not accessible (buried in resources/common.js) and not really related to mapping things. If we want to have examples that demonstrate how formats can be used to serialize features, a simple textarea would suffice as the target.
The projection option for vector file sources currently has no good meaning. The reprojectTo option is used to set the projection for cached features. This change makes it so the projection option is used for this purpose. The getProjection method (not currently exported) can then be used to get the cached feature projection.
This also removes the default of 'EPSG:3857' for vector file sources. If a projection is not configured, features will not be transformed.
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.
