/// A widget showing a loading spinner.
/// 
/// 
/// 
/// The size of the spinner depends on the available size, never smaller than
/// 16×16 pixels and never larger than 64×64 pixels.
/// 
/// Use the ``halign(_:)`` and ``valign(_:)``
/// properties in combination with ``widthRequest(_:)`` and
/// ``heightRequest(_:)`` for fine sizing control.
/// 
/// For example, the following snippet shows the spinner at 48×48 pixels:
/// 
/// ```xml
/// <object class="AdwSpinner"><property name="halign">center</property><property name="valign">center</property><property name="width-request">48</property><property name="height-request">48</property></object>
/// ```
/// 
/// See `SpinnerPaintable` for cases where using a widget is impractical or
/// impossible, such as ``paintable(_:)``.
