Path-based entitys

A brief overview of path-based entity functionality

Path-based entitys that use SVG d strings

• Shape

Path-based entitys mapping to Canvas API primitive paths

• Line
• Quadratic
• Bezier
• Using reference positioning for control points

SC pre-defined path-based entitys

• Cog
• LineSpiral
• Oval
• Polygon
• Rectangle
• Spiral
• Star
• Tetragon

Other things

• Polyline - generating a path-based entity from sets of coordinates (which can be references to other artefacts, and even particles)
• Loom - a compound entity that uses path-based entitys to define its display shape
• EnhancedLabel - can use path-based entitys for "text along a path" effects

Maybe include some thoughts on why SC doesn't support importing SVGs into the system, and will never support exporting canvas displays as SVGs.
