Now it works more like StubStyleObserver: you can assign std::functions to specific slots based on resource type.
Rewrite resource loading tests in that style, making them less like integration tests of Style and more like unit tests of Source, GlyphStore, and SpriteStore.
Updating glyphs is still unsupported, and there's no good use case for doing so. When we're using a stale glyph PBF, and the fresh answer contains changed to that glyph, we will continue to use the old glyph.
* Standardize on std::exception_ptr as the error representation
(fixes#2854).
* Don't format textual strings at the error source; pass on the
constituent data via observer method parameters instead.
* Use the null object pattern to simplify observer notification code.
* Further refactoring for ResourceLoading tests.
It's a premultiplied image. This implies that we were misusing encodePNG
in most cases, as we were passing premultiplied pixels which were then
interpreted as unmultiplied. I changed encodePNG to accept premultipled
pixels, and unpremultiply in the implementations.
ConstrainMode gives flexibility to our engine to choose between
constraining both vertically and horizontally, or just vertically
(default behavior).
Constrain in both axis means we can no longer pan the map beyond the map
boundaries. This fixes an issue where e.g. annotations disappear upon
crossing the map boundaries.
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.
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.
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.

This will make the code a lot more clear and it will
also move how parsing is initiated to the GlyphPBF
class, to be initiated after the request, like we do
for other resources.
this makes sure that adding custom sprite imagery will add them to the new Style object rather than
the old one in case a user adds new custom sprites immediately after changing a stylesheet
