Document/Clarify feature.id in return value of queryRenderedFeatures for vector sources.

[mb12]

mapbox-gl-js version:Master

Steps to Trigger Behavior

Can you please clarify/document if feature.id returned by queryRenderedFeatures is the following (or not) and if the client applications can use it this way?

feature.id is the index in the corresponding source layer in vector tile.

Expected Behavior

Actual Behavior

[jfirebaugh]

feature.id is the index in the corresponding source layer in vector tile.

No, it's the id property of the feature, as defined in the vector tile or GeoJSON specifications.

See #2716 for current caveat.
