基于 WebGL 的矢量地圖，Mapbox GL 0.9.0 發布

Mapbox GL 是基于 WebGL 的客戶端矢量地圖，也是個 JavaScript 庫。

Mapbox GL 0.9.0 發布，更新內容如下：

• glyphs URL now normalizes without the /v4/ prefix for mapbox:// urls. Legacy behavior for mapbox://fontstacks is still maintained (#1385)

• Expose geojson-vt options for GeoJSON sources (#1271)

• bearing snaps to "North" within a tolerance of 7 degrees (#1059)

• Now you can directly mutate the minzoom and maxzoom layer properties with map.setLayerZoomRange(layerId, minzoom, maxzoom)

• Exposed mapboxgl.Control, a base class used by all UI controls

• Refactored handlers to be individually included in Map options, or enable/disable them individually at runtime, e.g. map.scrollZoom.disable().

• New feature: Batch operations can now be done at once, improving performance for calling multiple style functions: (#1352)

  style.batch(function(s) {     s.addLayer({ id: 'first', type: 'symbol', source: 'streets' });     s.addLayer({ id: 'second', type: 'symbol', source: 'streets' });     s.addLayer({ id: 'third', type: 'symbol', source: 'terrain' });     s.setPaintProperty('first', 'text-color', 'black');     s.setPaintProperty('first', 'text-halo-color', 'white'); });

• Improved documentation

• featuresAt performance improvements by exposing includeGeometry option

• Better label placement along lines (#1283)

• Improvements to round linejoins on semi-transparent lines (mapbox/mapbox-gl-native#1771)

• Round zoom levels for raster tile loading (2a2aec)

• Source#reload cannot be called if source is not loaded (#1198)

• Events bubble to the canvas container for custom overlays (#1301)

• Move handlers are now bound on mousedown and touchstart events

• map.featuresAt() now works across the dateline
