The standard toolbar already provide zooming functionality, but this layer
comes to complete the latest.
When this layer is attached and active, zooming functionality could be used anytime. To zoom in x2 you must press the + key on your keyboard. To zoom
out x2 you must press the - key on your keyboard. You can also use the mouse
to zoom to a region defined by one rectangle. To define the rectangle you
must press Ctrl+LeftMouseButton for the first corner of the rectangle, you
may release, then move, then press Ctrl+LeftMouseButton once again to define
the second corner.
