Zoom in further over tiles layer #10

Hi, i'm using leaflet 0.7.3 and Leaflet Boundary Canvas to render some tile layers over a map via WMTS. When I zoom in until level 20, the layer disappears and shows up Google Map. According to Leaflet Documentation this problem is solved setting a value to maxNativeZoom property which prevents more server requests after level 18 but I tried to increment the maxZoom value in order to zoom in to layer and didn't work. So, if I remove this plugin, the zoom works.

I want to zoom in further with out losing the tile layers, i'm ok if the layer gets some blur.

The problem is similar to this: http://jsfiddle.net/gwacker/3kWRy/ (The layer disappears when zooming in)

The Layer options:

{
    tiled: true,
    format: 'image/png',
    transparent: true,
    tileSize:256,
    maxZoom: 20,
    maxNativeZoom: 18
}

The plugin uses L.TileLayer.Canvas class for Leaflet v0.7.x. Unfortunately, L.TileLayer.Canvas doesn't support maxNativeZoom option. I don't think that it is reasonable to modify original code of this class in plugin or to write PR to Leaflet...

But maxNativeZoom option works properly in Leaflet v1.0-beta! Maybe, you can use this new version in your project...
