Struct SyncPhysicalRectAu 

pub(crate) struct SyncPhysicalRectAu(PhysicalRect<AtomicI32>);

A PhysicalRect<Au> with shared mutablitiy

It is based on AtomicI32 but is not atomic itself: there is no protection against tearing: If multiple threads are calling set(), the rectangle may end up with some fields from one call and some fields from another call.

Compared to AtomicRefCell<PhysicalRect<Au>>:

• Both are meant for uses where despite shared ownership, no concurrency is expected in practice.
• If concurrent access does unexpectedly happen AtomicRefCell will panic, whereas SyncPhysicalRectAu can tear and result in invalid/inconsistent data.
• SyncPhysicalRectAu has no space overhead, AtomicRefCell stores an AtomicUsize borrow flag
• SyncPhysicalRectAu uses relaxed atomic access for each field separately
