  19.  * Marker manager is an interface between the map and the user, designed
    20. 

  20.  * to manage adding and removing many points when the viewport changes.
    21. 

  21.  *
    22. 

  22.  * Algorithm: The MM places its markers onto a grid, similar to the map tiles.
    23. 

  23.  * When the user moves the viewport, the MM computes which grid cells have
    24. 

  24.  * entered or left the viewport, and shows or hides all the markers in those
    25. 

  25.  * cells.
    26. 

  26.  * (If the users scrolls the viewport beyond the markers that are loaded,
    27. 

  27.  * no markers will be visible until the EVENT_moveend triggers an update.)
    28. 

  28.  *
    29. 

  29.  * In practical consequences, this allows 10,000 markers to be distributed over
    30. 

  30.  * a large area, and as long as only 100-200 are visible in any given viewport,
    31. 

  31.  * the user will see good performance corresponding to the 100 visible markers,
    32. 

  32.  * rather than poor performance corresponding to the total 10,000 markers.
    33. 

  33.  *
    34. 

  34.  * Note that some code is optimized for speed over space,
    35. 

  35.  * with the goal of accommodating thousands of markers.
