Point::scaled()

Hi Jules,

Even though this has (most likely) limited use, I would like to suggest adding the following to Point:

Point scaled (ValueType scale) const noexcept { return Point (x * scale, y * scale); }

Point scaled (ValueType scaleX, ValueType scaleY) const noexcept { return Point (x * scaleX, y * scaleY); }

It already has operator* and operator*= to do those ops.
