PNGs for the toolbox icons for the different connector types.

Their appearance can be seen in https://www.omg.org/spec/DMN/1.1/PDF (page 30, "Association", "Information Requirement", "Knowledge Requirement" and "Authority Requirement"). They'll only be used as icons on the toolbox (see screenshot attached). Could you please also remind me of the BAPL for the new "Node" SVGs (I'll need to make PNGs of those too for the same "toolbox" purpose.. unless UX have a tool to convert SVG to PNG?)
