The externs/olx.js script includes @typedef annotations for objects that are used in the library. When compiling the examples together with the library, we need these @typedef annotations. In this same case, we don't need the object property names to be treated as externs (they can be safely renamed).
The single externs/olx.js file describes all of the "options" objects we accept in our constructors. The @typedef annotations are used by the compiler for type checking. The @type annotations include documentation for individual options and serve as externs when compiling a profile of the library. When compiling an application together with the library, the externs/olx.js file is included as one of the sources to provide the @typedef's without generating externs.
If we want to maintain multiple src/*.externs.js files instead of one large externs/olx.js file, we can. But while we are still using Plovr, it makes for easier build configurations to have one file.
This removes the build tasks that generated the build/src/external/src/externs/types.js and build/src/internal/src/types.js files as those are both replaced by the single externs/olx.js file.
This strips markup from elements with id attributes that we care about: title, shortdesc, tags. This will only work for people who use `npm install && npm start` to browse examples. The other example parser doesn't strip this markup, so it should still not be used in these elements.
With this change, it is more straightforward to determine
whether an event is considered as handled, which results in the
removal of the modifiable_ and lastVertexCoordinate_ states.
Instead, we only need to know whether we're on a real vertex or
a virtual one. For that a new snappedToVertex_ flag is
introduced.
To stop a click after vertex deletion from triggering a feature
selection, vertex deletion is now triggered by a configurable
event condition, which defaults to singleclick (same as in the
select interaction) with no modifier keys.
