This follows the convention in the Closure Library of providing either namespace objects (where the property starts with a lowercase letter), constructors (where the property starts with an uppercase letter), or enums (all uppercase properties, only one instance of this in the closure library).
A 'this' identifier is quite useless with compressed JavaScript,
and in fact it turned out to fail in advanced mode when trying
to access a feature's renderIntent property with it. The added
renderIntent lib function as a Call expression does the job
well.
With this change, the user provides a filter function instead of
an array of layers. Selection layers are created lazily, and
addition/removal of layers is not handled by the control to give
the user more options, as suggested by @elemoine.
I'm adding this example to demonstrate a few things that should change:
* the icon symbolizer should accept xOffset and yOffset in pixels
* the `ol.geom.Geometry.prototype.getCoordinates` method should be exported
* overlays should have a `panIntoView` method
This commit changes the examples to using ol.control.defaults().extend to extend the collection of controls. This is in preparation for a future commit that will remove the 2nd argument to ol.control.defaults. The same is done for ol.interaction.defaults.
Currently the animation functions share the same module, namely ol.animation. We do differently for ol.control.defaults and ol.interaction.defaults, with ol.control.defaults and ol.interaction.defaults module. This commit replaces the ol.animation module by four modules, one for each animation function.
This makes things more consistent, and will make it possible to use the @exportFunction annotation for the exporting of the animation functions.
