Now vector layers can have a style. ol.Style instances have an
apply method to get the symbolizer literals for a feature. If the
layer does not have a style defined, there is also a static
applyDefaultStyle function on ol.Style to get the default
symbolizer literals for a feature. The vector layer also got a
groupFeaturesBySymbolizerLiteral method, which returns an array
with features grouped by symbolizer, as needed by the canvas
renderer.
Currently only renders points as circles. Eventually will have methods for other geometry types and other symbolizer types. Also provides static methods to render point symbolizers (returning a canvas that can be drawn on another).
