 I might be wrong, but OL does not provide a way to alter a feature's
 geometry based on the context it is being drawn.
 Between the call to layer.drawFeature and the actual drawing from the
 renderer, there is no way to change geometry.
 This means that for instance, you cannot modify the geometry based on the
 current map state, resolution, etc.
 In my case, I want to handle a custom "arrow" shape. But I just can't
 because I need to update the shape knowing the current resolution of the
 map and OL does not allow this AFAIK.
 Besides, there is no way to add new geometry types because the way
 geometries are drawn is directly controlled by the renderer itself.
 If geometries could have a "draw" method and renderer would call this
 method then we would have a way to extend geometries.
