Individual layer renderings

The MapCanvas class described previously was responsible to define a common coordinate space and combining the images of its layers, but not for any actual drawing. We leave this task to the individual layer classes, one for vector and one for raster.

Vector layers

The rendering of vector data is fairly easy. All we have to do is create a VectorLayer instance around the VectorData class, and optionally decide some style aspects of its geometries using keyword arguments. During this style options stage, we allow all features being styled in the same way.
