v0.3.3 - Added arc_to_cubic.py module to convert elliptical arcs to cubic bezier curves. Convert arcs to cubics before drawing SVG path onto a skia SkPath and remove use of convertConicsToQuads in most places where we interact with pathops, except when stroking (round linecaps can introduce conics) (#7). - tonanosvg() now always applies transforms before ungrouping (#5). - Fixed bug in resolve_use where an unqualified 'g' element was being added, which made ungroup method miss it when xpath-ing with svg namespace (#5).
