Change subject: [BREAKING CHANGE] Allow target widgets to be re-used
......................................................................
[BREAKING CHANGE] Allow target widgets to be re-used
* Introduce #setDocument that re-creates the surface
but keeps the toolbar.
* Make initial doc an optional config parameter.
* Re-emit history event so user doesn't have to re-bind
when surface is changed.
This is a breaking change as it changes the constructor
signature.
