All Transform methods that take a PrecisionPoint now assume a “flipped” origin at the upper-left corner of the view. Previously, some methods assumed an origin at the lower-left corner.
Eliminated many redundant methods on Transform. Minimized usage of TransformState::x and TransformState::y. Added convenient constructors for AnimationOptions. When scaling, passing in view’s origin as the anchor no longer anchors the scaling operation at the view’s center. To specify no anchor, use NaN.
Increased precision of worldSize(), now that it’s used much more heavily in transform methods.
* Move asset:// URL handling to DefaultFileSource.
* AssetFileSource implements FileSource interface and follows familiar implementation patterns.
* Move default implementation to platform/default, zip implementation to platform/android.
* Don't bother with modified / expires / etag -- assets are not cached so it doesn't matter.
* Don't bother with interleaving individual IO calls on the implementation thread. That adds a lot of complexity for very little benefit.
Even if the map supports wrapping the world, it isn’t necessary to show more than one full revolution of the world at a time. Removed a redundant zoom level clamp.
If for whatever reason a source doesn’t cover all the zoom levels allowed by the style – for instance, if different sources have different zoom ranges – use the nearest available zoom level.
* 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.
Greatly simplified conversions between zoom level and altitude. Adjusted field of view to more closely match MapKit. Conversions are now well within the same order of magnitude as MapKit at all latitudes.
Fixes#2266.
The speed and curve fields in CameraOptions have been replaced with velocity and minZoom fields, which expressed in screen units. Scaling and easing make it difficult to derive options that are expressed in physical units.
Rewrote the flyTo implementation to more closely match GL JS’s implementation and the paper on which it is based.
Rewrote CameraOptions documentation. Only document units for generic types like double. The semantics of LatLng and Duration are already baked into the types; one just needs to look up the types’ definitions. Also, the […) is set notation, so the braces are supposed to be mismatched.
Fixes#3296.
