Plugin to make it easier to create SVG files. The elements and properties have been organized in different menus, each menu being dedicated to a specific broad theme: "text", "shapes", "filters", "animation" etc. Each of the several thematic menus includes all the entities and properties relevant to the subject, and conversely elements and properties are duplicated on all the menus where they are relevant: e.g. the fill property is applicable to text and shape elements, so it appears in these two menus (at least). Whenever applicable, tag text written into the SVG document includes all the predefined values assumed by the SVG specifications.
