Adjustment for the minimum zoom level to prevent gray bands
This patch introduces a lower bound for the minimum zoom level of
a map element so that it becomes canvas size dependent, and it will also
prevent the map from being smaller than the canvas size in either
dimension, avoiding gray bands.
It also bounds the center of the map so that the map cannot be panned or
flicked out of bounds.
The documentation for QDeclarativeGeoMap::minimumZoomLevel has been
modified to reflect the new behavior.
A few testcases have been modified to reflect this new behavior and its
implications.
