+ Converts the given [param variant] to the given [param type], using the [enum Variant.Type] values. This method is generous with how it handles types, it can automatically convert between array types, convert numeric [String]s to [int], and converting most things to [String].
+ If the type conversion cannot be done, this method will return the default value for that type, for example converting [Rect2] to [Vector2] will always return [code]Vector2.ZERO[/code]. This method will never show error messages as long as [param type] is a valid Variant type.
+ The returned value is a [Variant], but the data inside and the [enum Variant.Type] will be the same as the requested type.
