1//! Not from the reference: the handle of a writeable bitmap that the `Bitmap` properties of the
2//! writeable bitmap behaviors, triggers and actions hold.
3//!
4//! Deviation (DEVIATIONS.md, Behaviors): a property value is cloned and compares with `==`; a
5//! [`WriteableBitmap`] of the framework is neither, so the properties typed `WriteableBitmap` in
6//! the reference hold this shared handle, which compares by identity as the reference compares
7//! its object references.
