Editor + Runtime Feathers!

Adds feathering support to the runtime and editor.

A few important changes:
- Runtime now deals in RawPaths via ShapePaintPath. We no longer store a bunch of RenderPaths that we don't always end up using. Instead we use a light wrapper around RawPath (ShapePaintPath) to track intention of space (local, world, etc) and fill rule for the path so the runtime can pass that around and further mutate it or upgrade it to an immutable RenderPath only when it wants to actually draw it.
- Stroke effects like Dash and Trim now build on the update instead of render!
