* [ios, macos] Source-driven attribution
Refactored MGLSource initialization. Implemented a new private class, MGLAttributionInfo, that parses an HTML attribution string from TileJSON and stores the resulting structured data. Added methods to MGLTileSet and MGLStyle to aggregate MGLAttributionInfos.
On macOS, update the attribution view as soon as the source attribution changes. On iOS, fetch the current attribution information when displaying the action sheet.
Removed hard-coded attribution strings.
* [macos] Respect inline formatting in attribution HTML
Apply a default font and color to attribution HTML as it is imported into an attributed string. Pass the attributed string into MGLAttributionButton as is, without stripping formatting. Avoid overriding the font and color after importing the HTML, in case these attributes are explicitly specified rather than intrinsic to a hyperlink.
Constrain the top of the attribution view to all the attribution buttons, in case one of them needs additional headspace.
* [ios, macos] Display unlinked attribution strings
Unlinked attribution strings are represented on macOS as buttons that have the default cursor and do nothing when clicked. On iOS, they are action sheet buttons that do nothing but dismiss the action sheet.
* [macos] Fixed random Auto Layout exception
Auto Layout randomly finds itself unable to satisfy constraints when updating attribution, due to some spurious constraints between attribution buttons. Regenerate the entire attribution view every time the source attribution changes.
* [ios, macos] Thoroughly dedupe attribution infos
Also added a test to verify parity with the GL JS implementation. This implementation avoids sorting.
* [ios, macos] Trim whitespace from attribution strings
Also added parsing tests.
* [ios, macos] Added attribution parsing tests for styles
Included an emoji test to ensure that attribution strings are interpreted as UTF-8, to avoid mojibake. Included a test of removing the underline from a leading copyright symbol.
* [ios, macos] Derive feedback link from source
MGLAttributionInfo now detects feedback links in the attribution HTML code, and it is responsible for tailoring the feedback URL to the current viewport.
Removed the hard-coded feedback action from the attribution sheet on iOS in favor of a source-derived feedback title and URL. Moved the feedback action from macosapp to MGLMapView; applications are now expected to hook an Improve This Map menu item to an MGLMapView action.
* [android] - remove location enabled flag from MapboxMap, decouple TrackingSettings from MyLocationViewSettings using a FocalPointChangeListener interface, Move state related to tracking modes to MyLocationView (shared object between MyLocationViewSettings and FocalPointChangeListener).
* fixup tests
* [ios, macos] Replaced custom style layer API with MGLOpenGLStyleLayer
Replaced the custom style layer API on MGLMapView with an equally unsupported MGLOpenGLStyleLayer API that nonetheless is consistent with the broader runtime styling API and is compatible with macOS.
Fixed an unrecognized selector crash when wrapping a layer of unrecognized type coming from mbgl.
* [macos] Added lime green layer demo to macosapp
Reprised the demo removed from iosapp in #5091.
* [ios, macos] Rationalized MGLOpenGLStyleLayer API
MGLStyle now strongly references any MGLOpenGLStyleLayer object that’s added to it, in order to prevent pointers from going stale and make it easy for layer drawing code to get more information about the map view. Replaced the MGLOpenGLStyleLayer callback blocks with overridable instance methods. Added internal documentation for each method. Subclassed MGLOpenGLStyleLayer as LimeGreenStyleLayer inside macosapp.
Consolidated -addToMapView: into -addToMapView:belowLayer: to ensure that MGLRedundantLayerException gets raised even if the layer is being inserted rather than added to the bottom of the stack.
* [core] Clarified that rendering happens on the main thread
* [ios, macos] Fixed removing and re-adding MGLOpenGLStyleLayer
Don’t allow index-based layer removal to circumvent -removeFromMapView:, which MGLOpenGLStyleLayer relies on to synchronize the style’s array of MGLOpenGLStyleLayers. When obtaining an MGLOpenGLStyleLayer, get the instance already added to the style instead of creating a new one to wrap the underlying CustomLayer.
* [ios, macos] Completed API for mutating multipoints
Added the complete set of methods for mutating the vertices of an MGLMultiPoint. Also rewrote MGLMultiPoint documentation to refer to vertices instead of points.
* [ios, macos] Removed inaccurate MGLOverlay commentary
This paragraph is full of references to features that exist in MKOverlay but not MGLOverlay.
* [ios, macos] Lazily compute multipoint bounds
Invalidate the bounds whenever the coordinates change, but don’t recompute the bounds until they’re requested. Simplified -intersectsOverlayBounds: for immutable overlay classes.
Added a utility function for testing whether two MGLCoordinateBounds intersect, based on mbgl::LatLngBounds::intersects().
Removed unused color conversion code.
Documentation for attributes whose names we’ve overridden now mention the original style specification property name, with a link to the style specification documentation for the property.
* [core] Add interface to get image from sprite atlas
* [tests] Add tests for Map::getImage
* [ios, macos] WIP: get MGLImage for name from style
* [ios, macos] Fixed -imageForName:
Convert from sprite images to platform images using the existing encodePNG() function, which is also used for printing. Allow -imageForName: to return nil without an assertion failure. Added a basic test.
