_checkZoomLevels breaks on fractional zoom
As seen in demo.html (zoomSnap: 0.25
).
When zooming in/out this conditions became false

I'm not exactly sure how that was supposed to work. As per docs Google map can be set up support fractional zooming (in beta channel): https://developers.google.com/maps/documentation/javascript/reference/map#MapOptions.isFractionalZoomEnabled (I failed to do that, but may be I haven't tried hard enough).
