[=] Wrap fix for #555

Browse Source 
1. Fix for horizontal and vertical wrap. Problem was in
`getTileAtPoint`: it was working only for points inside viewer - thanks
to @avandecreme for finding this.
2. Was small bug in not rendering top row and left column - after scroll
there are empty space and need some time for rendering.
