isWithinBlueDotProximityArea
Determines whether the given Mercator coordinate is within the user's blue dot error area and on the currently visible floor. This method performs the following: 1. Converts the Mercator position to a MapPos (Web Mercator). 2. Checks if the position lies within the error boundary polygon's bounding box. 3. Verifies if the user's current zone is valid and on the currently visible floor.
Return
true if the position is within the error area and on the correct floor, false otherwise.
Parameters
mercator
The Mercator coordinate (x, y) to test.
