RouteMarkersDisplay

@RestrictTo(value = [RestrictTo.Scope.LIBRARY_GROUP_PREFIX])

class RouteMarkersDisplay

Every time new visible segment is emitted this class tries to find a good position for label to display.

Method findRelevantPosition makes 5 attempts to find a point meeting the following criteria:

There is at least one position of four intercardinal direction – AltLabelAnchorCalculator is used to calculate those positions and it also sorts them descending according to available space around each label
Label should be clearly visible – no intersection with the edges of visible area (visible area is usually smaller than visible map as we don’t want labels to appear below UI elements like navigation guidance, button etc.)
