This fixes adding shape annotations after VectorTileData objects have
been created for annotations already, and will also be necessary for
the dynamic Style API.
To encapsulate the differences, this introduces an abstract
GeometryTileMonitor class, with concrete VectorTileMonitor and
AnnotationTileMonitor implementations, and makes pbf parsing for
VectorTile data happen lazily in getLayer, since we want that to
happen on the worker thread, rather than when VectorTile is created.
Fixes#2792
The location under your finger stays under your finger as you pan.
The location you double tap to zoom stays at the same point.
The location at the center of a pinch zoom stays at the center.
The location at the center of a rotation stays at the center.
We're now reparsing tiles when they expire. We're also swapping out buckets atomically to avoid flickering data; i.e. we're displaying the old data as long as we don't have a new parsed bucket for that layer yet. The parsed buckets now live in the *TileData objects rather than in the TileWorker; only partially parsed == pending buckets will remain in the TileWorker. Once they're parsed, they're moved to the *TileData object.
We're now returning stale responses from cache. Those responses will have the `stale` flag set to true. Currently, all requesters in the core code discard stale responses, and cancel the request immediately after they got a non-stale response.
By not automatically destroying Request objects after the result has been delivered, we are making sure that we can potentially fire the callback multiple times without adverse effects. This means that you have to hold on to the result of fs->request(), can explicitly cancel it if you don't want to be notified of data changes anymore. Not doing so will monitor the request indefinitely and will prevent the app from exiting.
Adding new mbgl::GLContextMode enum to mbgl::Map ctor, which gets stored
in MapData. In shared GL context environments, we cannot assume that the
GL state that has been left since the last draw is the same, so we reset
the GL configurations to their default values.
Attempting to use a Mapbox-hosted incompatible raster map/style with GL
would throw a simple 404, without any indication of the real issue.
Fix#1724, ref #1841
This condition led to layers with high minzoom like oneway street
arrows (z15) get parsed and placed regardless of minzoom (e.g. z11+),
wasting a lot of worker CPU time.
It became unnecessary after we added reparsing tiles when overscaling,
and even before that it should have probably been <= rather than <.
First, move style mutation code out of StyleParser and into AnnotationManager,
coalescing it with the mutation code for shape layers.
Second, allow AnnotationManager to keep track of stale tiles entirely
internally. There's no reason to pass sets of TileIDs around.
Third, correct the logic for invalidating the shape source. Since
AnnotationManager does not track shape invalidations on a tile-by-tile basis,
don't try to invalidate the shape source tile-by-tile.
