An interface that may be implemented by a wl_surface, for

It provides requests to treat surfaces like windows, allowing to set

them, and associate metadata like title and app id.
|
|
|
|
On the server side the object is automatically destroyed when

constrainment and alignment.
|

CSD often has invisible areas for decoration purposes, like drop

shadows. These "shadow" drawings need to be subtracted out of the

normal boundaries of the window when computing where to place

windows (e.g. to set this window so it's centered on top of another,

This value should change as little as possible at runtime, to

fullscreen, and assumed to be 0.

Desktop environments may extend this enum by taking up a range of
