Re: [Vala] about property override.

[Conrad Um <conr2d gmail com>]

Property which can be overriden is marked with `virtual` modifier in parent
class. In that case, you can override it by `override` modifier.

For instance,
  class Foo {
    public virtual int some { ... }
  }
  class Bar : Foo {
    public override int some { ... }
  }

If property doesn't have `virtual`, it means that the author of parent
class designed the property not to be overridable.
You can add a property having same name by `new` and shadow original
property, but internal methods in parent class won't refer to your new
property, but to original one.
