From subtle glow, to pronounced outlines or drop shadows — apply filters to relevant marker types to improve annotation legibility or just simple visual flare. Now available in v3.3.

marker.js always had a rectangular highlight marker but the one resembling a physical highlighter was not on the menu. That changes in v3.2.
