Zoom Progress: Actor/Link Tool Hitboxes 

* When the Actor Tool or Link Tool is active, mouse-over hitboxes on the
  level's actors now works correctly while zoomed and scrolling in the
  level.
* Regression: Level chunks don't appear outside a certain range from
  origin while zoomed in.
* Regression: Actors don't draw their sprite while zoomed in, but do
  when zoomed out.
