<description summary="Create remote desktop-style surfaces">
remote_shell allows clients to turn a wl_surface into a "real window"
which can be stacked and activated by the user.
Warning! The protocol described in this file is experimental and backward
incompatible changes may be made. Backward compatible changes may be added
together with the corresponding interface version bump. Backward
incompatible changes are done by bumping the version number in the protocol
and interface names and resetting the interface version. Once the protocol
is to be declared stable, the 'z' prefix and the version number in the
protocol and interface names are removed and the interface version number is
reset.

<description summary="set window bounds">
Set the "visible bounds" of a window from the user's perspective.
Client-side decorations often have invisible portions like drop shadows
which should be ignored for the purposes of aligning, placing and
constraining windows.
The bounds are double buffered, and will be applied at the
time wl_surface.commit of the corresponding wl_surface is called.
Once the bounds are set, it is not possible to unset them, and they will
remain the same until set_bounds_in_output is called again, even if a new sub-
surface or buffer is attached.
If never set, the value is the surface content bounds. This updates
dynamically on every commit.
The bounds are relative to the given display. If the display is invalid,
they are assumed to be relative to the primary display.
The width and height must be greater than zero.

<request name="set_scale_factor" since="4">
<description summary="Allows the client to set the scale factor for the future buffer commits.">
The client has a 32-bit float scale factor that is associated with each
remote surface. This scale factor must be propagated exactly to exo. To
do so we reinterpret_cast into a 32-bit uint and later cast back into a
float. This is because wayland does not support native transport of
floats. As different CPU architectures may use different endian
representations for IEEE 754 floats, this protocol implicitly assumes
that the caller and receiver are the same machine.
This is double buffered state and will be applied in the next commit.
