add GeomBuilder, needs Jts drawing_api: squashed drawing_api: use JtsDrawable baseclass - add makeCircle for testing drawing_api: cleanups drawing_api: refactor drawing_api: use SpatialIndex drawing_api: optimization + cleanup drawing_api: VectorLayer - use VectorLayer for PathLayer drawing_api: make style builder more consistent with theme api drawing_api: wip
