Florin Malita 45cd20004c [skrive] Initial artboard plumbing
"Artboards" are top-level Rive containers (similar to AE compositions),
holding the scene graphics and related animations.

Artboard properties:

  - name
  - width/height (size)
  - translation (position)
  - origin (anchor point for transforms?)
  - (background) color
  - clip contents flag

Plumb artboard parsing + background rendering, and hook into viewer.
