Consolidate localization behavior and init to a coreLocalizer function and singleton
Explicitly support `en-US` locale
Rename coreData to coreFileFetcher and export a singleton rather than using a property of coreContext
Add `apiConnections` property of coreContext to simplify adding a source switcher
Replace some init functions with re-callable, promise-supporting `ensureLoaded` functions
Make coreContext itself load the UI if a container has been specified at init time
Fix code tests
Fix issue where double-tap-to-zoom would not be properly disabled when drawing on touch devices (close#2128)
Support adding nodes to ways with double-tap with on touch devices (close#2677)
Support double-tap-to-zoom with styluses on touch devices
Don't accept double click/tap events if the taps are far apart
Don't re-enter modeSelect when clicking the selected feature again
- When drawing an Area, the leading edge is allowed to temporarily be in an invalid position (see #4655)..
.. Finishing a drawing is disabled if doing so would close with the invalid leading edge
(closes#4669)
Now instead of creating MultiLineString targets, we just create a bunch of
LineString targets. This makes the code simpler, and anyway the entity is
still there in `properties` for drawing code to decide what to do with the target.
Incidentally, this change allows iD to support an extrusion operation.
(Because each way segment has its own unique GeoJSON target now)
This makes the code a bit more consistent and lets us avoid some
hacky and probably non-performant things:
- abusing CSS classes in the draw/drag datum functions (classed `.target`)
(is this thing target? just check d.properties)
- regexing the id for `-nope$`
(is this thing a nope target? just check d.properties)
- using context.hasEntity to get a the real entity
(is this thing a real osmEntity? just check d.properties)
- fixes code like the restriction editor which uses fake ids for split ways
The goal here is that the code that draws the targets should know better
what parts of the lines/vertices are targetable, rather than just
relying on CSS to ignore the pointer events on the whole line.
e.g. when drawing a line, it's ok for it to loop back and connect
to itself, just not on a segment or vertex adjacent to the active
node.
