Give Geolocation Control Marker Pitch Alignment Properties

[JohnCLo]

Currently when the geolocation control marker is added to the map, the blue marker has no options to change color or set pitch such as "circle-pitch-alignment": "map". For aesthetic purposes, it may be useful for the marker to have more paint options that are exposed to a normal circle type layer.

Current:

The dot is implemented as a Marker (

mapbox-gl-js/src/ui/control/geolocate_control.js

Line 284 in c605974

this._userLocationDotMarker = new Marker(this._dotElement);

) so you can't use the normal pitch-alignment capabilities of using a Circle from the style spec, this would need to be implemented by watching the pitch change and updating the CSS of the Marker.

Originally the dot was done as a Circle, but due to issues with injecting this into the users style, we made it a Marker.
