In user tracking mode, keep the user dot in a fixed location on screen, instead easing the map view so that the fixed location corresponds to the new user location. There is one exception: MGLMapView reacts to the first location update the same way as before, so that it appears to move to where the user dot has been all along.
In course tracking mode, weight the user dot down towards the bottom of the view, since it’s more important to see the road ahead than the road behind.
Fixes#2600, and #1041 to some extent.
The main loop will now wait for all the requests to
complete before closing.
This will make the FileSource on OSX block longer than
it should at shutdown.
Should not be used at all, added for a corner case
on OSX network backend where the request is processed on
a worker thread managed by OSX and we need to wait for
that reply before destroying the thread that pushed the
request.
This reverts commit 6709bdcacd.
There was an issue with the script that removes '-lwebp' from WebP
linker flags, since we're statically linking. This is now fixed.
The zoom level is already clamped by Transform. -currentMinimumZoom appears to be useful only as an unrotation threshold; it doesn’t correspond to the minimum allowed zoom level.
Map and Transform methods assume an origin at the top-left corner of the view, like iOS, Android, and GLFW but unlike OS X. Transform is responsible for flipping coordinates between the top-left origin of Map and the bottom-left origin of TransformState.
Fixes#3574.
Methods that offer a convenient way to jump or ease now accept an optional padding parameter. MGLMapView specifies the padding to ensure that keyboard-based zooming and rotation respects the toolbar.
Added a contentInsets property to MGLMapView that behaves similarly to NSScrollView.contentInsets. Adjust it according to the window’s content layout rectangle using KVO. Automatically apply the content insets whenever creating a CameraOptions or getting the center coordinates.
Moved EdgeInsets to geo.hpp so CameraOptions and Transform can refer to it. Added a padding option to CameraOptions that alters the frame of reference for the center option. Added optional padding parameters to LatLng getters and setters.
Working towards #2600.
Avoid unrotating due to programmatic rotation, even programmatic rotation that might expose empty portions of the map. Only snap to north due to a gesture.
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.
Previously, we could first get a stale response from cache, then immediately a "connection error" response that overwrote the error state variable. In the tileLoadingCompleteCallback, we'd only see the second overwritten error state and abort. This could lead to the map sometimes not being rendered at all until the user interacts with the map.
This is a naïve implementation that essentially merges updated data into existing data. It will *not* remove icons from the stale sprite if they aren't present in the fresh sprite (we aren't tracking the source of a sprite, and the user could have changed it as well). Similarly, it will not update icons that have changed in dimension. This is a rare edge case and probably not worth implementing.
Otherwise, this will remove them from the map and overwrite the old data. This could happen e.g. when we have connection trouble and a tile needs to be refreshed, or we're displaying stale information and the connection is down.
We're now supporting using stale TileJSON and GeoJSON data. When we receive a new answer with an updated TileJSON file, we're replacing the Source's metadata with the new one and trigger updates to make sure we're loading the correct tiles. Similarly, GeoJSON data will be reparsed.
This adds support for using cached styles that are stale. They're treated like changing styles; when the refreshed style changed compared to the one we've already had, we're swapping out the entire style, which might cause a slight flicker.
If you use many different caches, expired weak_ptrs will pile up in the unordered_map, but that is an edge case, and you probably shouldn't do that anyway.
Previously, the placement of symbols depended on the order in which the
glyphs they need were loaded. The placement order should be based on the
style.
To fix this, symbol layers are placed in `placementPending` after they
are parsed. After all layers are parsed, symbol layers (stored in
`placementPending`) are placed and returned.
