- Zoom: pass panActivationKeyPressed so Control can activate pane panning
  with a primary-button drag (new PanZoomUpdateOptions field in 0.0.80)
- Pane: prefer touch panning over drag selection (no more selection box
  when panning via touch with mouse-button-specific panOnDrag)
- system 0.0.80 also brings: middle-mouse panning from selection rects,
  extent:'parent' with intrinsic parent size, getNodesBounds skipping
  unresolvable ids
- add CHANGELOG.md, bump version to 0.1.1
