Build tools and sources for developing OpenLayers based mapping applications

# v3.13.0

## Summary

The v3.13.0 release includes features and fixes from 68 pull requests since the v3.12.1 release.  New features and improvements include:

* Improved tiles rendering for the canvas renderer
* Improved MapQuest rendering
* Add color option to ol.style.Icon
* Load TileJSON sources via XMLHttpRequest by default
* Add new ol.geom.LineString#getCoordinateAt function
* Simplify meters per unit handling
* Use ESLint as a replacement for gjslint.py and jshint

## Upgrade notes

#### `proj4js` integration

Before this release, OpenLayers depended on the global proj4 namespace. When using a module loader like Browserify, you might not want to depend on the global `proj4` namespace. You can use the `ol.proj.setProj4` function to set the proj4 function object. For example in a browserify ES6 environment:

```js
import ol from 'openlayers';
import proj4 from 'proj4';
ol.proj.setProj4(proj4);
```

#### `ol.source.TileJSON` changes

The `ol.source.TileJSON` now uses `XMLHttpRequest` to load the TileJSON instead of JSONP with callback.
When using server without proper CORS support, `jsonp: true` option can be passed to the constructor to get the same behavior as before:
```js
new ol.source.TileJSON({
  url: 'http://serverwithoutcors.com/tilejson.json',
  jsonp: true
})
```
Also for Mapbox v3, make sure you use urls ending with `.json` (which are able to handle both `XMLHttpRequest` and JSONP) instead of `.jsonp`.
