Compare this point with another point when the `x` and `y` values of both points are rounded. For example:
[100.3,199.8] will equals to [100, 200].
@param {Ext.util.Point/Object} point The point to compare with, either an instance
of Ext.util.Point or an object with `x` and `y` properties.
@return {Boolean}
