- Add the helper coordIsValid() and use it in centerOnCoordinate().
This checks for NaN coordinates and prevents an infinite while() loop.
- Use '-= 1.0' instead of '--' to be more clear that the decremented
variable is a float
- Store the current center with 'centerStored' in
centerOnCoordinate(). Fixes a possible zoom out glitch.
- use Math.floor() to convert 'zoomLevel' to integer when estimating
zoomOut in centerOn*()
