Instead of transforming between return value and callback, pass
the wrapped callback on to the invoked function as the last argument.
This eliminates the need for multiple invokeWithArgument overloads
and permits invoked functions to be asynchronous.
Calling setStyleURL() multiple times in a short period
of time will enqueue requests on the FileSource. The
order they get replied is not guaranteed to be the same
as the order we make the requests. The side effect was
the last style set not always being the one rendered.
Now we cancel the current request if we make a new one
(and there was no point on keeping it around anyway).
We now drive rendering from the main thread calling renderSync(),
but if we do it just after we set the style URL it will assert
because renderSync() expects the style to be fully loaded.
Whoever determined the boundaries of the District of Columbia did not have fit-to-bounds implementations in mind. With this change, shapes that are not unrotated rectangles fit much, much better.
Each side of the bounding box is specified independently, allowing more flexibility than the offset + padding construct supported in mapbox/mapbox-gl-js’ Camera.
The new implementation is now public and takes advantage of MGLCoordinateBounds. It is re-ported from `Camera.prototype.fitBounds()` in mapbox/mapbox-gl-js to ensure correct behavior. A new function, MGLCoordinateBoundsMake(), makes it easier to create an MGLCoordinateBounds for use with this method.
For now we set the FileSource for the Worker context
but in the future after fixing #1664 we can assert()
that FileSource are set only for the Map thread context.
Do not use the Environment anymore. The Environment ID is not
really necessary anymore as we are forwarding exceptions to the
main thread, so we always know which Map object triggered the
error.
mbgl::Thread will keep a ThreadContext for each running instance
in a thread_local so we don't need to lookup a man in the Environment
every time we need some info about the current thread.
This patch is moving the ::currentlyOn check used on Debug build from
the Environment class to the ThreadContext.
