Yes, that's normal. If you override one function in a child
class, you need to explicitly bring in the other overrides by
adding
alias texture = Control.texture; // I think you can also use
`super.texture`
in the class with the new override. That tells it to look up the
name from the parent as well.
The rationale is here: http://dlang.org/hijack.html
It isn't just properties btw, any case of overloads is subject to
the same rule.
