Support multiple origins

[maRci002]

Some goeserver changes origin based on zoom level.

      <TileMatrix>
        <ows:Identifier>EOV_teszt:0</ows:Identifier>
        <ScaleDenominator>7314285.714285715</ScaleDenominator>
        <TopLeftCorner>420000.0 564288.0</TopLeftCorner> <---- **0. zoom layer** ---->
        <TileWidth>256</TileWidth>
        <TileHeight>256</TileHeight>
        <MatrixWidth>1</MatrixWidth>
        <MatrixHeight>1</MatrixHeight>
      </TileMatrix>
...
      <TileMatrix>
        <ows:Identifier>EOV_teszt:2</ows:Identifier>
        <ScaleDenominator>1828571.4285714286</ScaleDenominator>
        <TopLeftCorner>420000.0 433216.0</TopLeftCorner> <---- **2. zoom layer** ---->
        <TileWidth>256</TileWidth>
        <TileHeight>256</TileHeight>
        <MatrixWidth>4</MatrixWidth>
        <MatrixHeight>3</MatrixHeight>
      </TileMatrix>
...

This happens when we reuse same origin(420000.0 564288.0) at each zoom level:
origin: [ 420000.0, 564288.0 ]

This happens when we apply to support multiple origins:

        origin: [ [ 420000.0, 564288.0 ], [ 420000.0, 564288.0 ],
				[ 420000.0, 433216.0 ], [ 420000.0, 433216.0 ],
				[ 420000.0, 400448.0 ], [ 420000.0, 384064.0 ],
				[ 420000.0, 375872.0 ], [ 420000.0, 375872.0 ],
				[ 420000.0, 375872.0 ], [ 420000.0, 375872.0 ],
				[ 420000.0, 375872.0 ], [ 420000.0, 375872.0 ],
				[ 420000.0, 375872.0 ] ]

At start of scale / zoom function maybe we could write something like this to avoid Leaflet function overrides:
this.transformation = this._getTransformationByZoom(zoom);

The map bounces a bit but the marker stays at the right place.
