Avoid canceling transitions (and triggering preexisting completion handlers) until we get a chance to ensure that a new transition really does have to begin. Consistently avoid mbgl transitions for redundant camera changes. Upon bailing, schedule the completion handler to run asynchronously on a delay equivalent to the requested animation duration.
Added a “functional” equality method to MGLMapCamera that avoids trivial differences.
Fixed invocations of XCTAssertEqualWithAccuracy() that incorrectly expressed the accuracy as a number of digits rather than a scalar tolerance.
