<description summary="protocol for creating temporary seats">
The transient seat protocol can be used by privileged clients to create
independent seats that will be removed from the compositor when the client
destroys its transient seat.
This protocol is intended for use with virtual input protocols such as
"virtual_keyboard_unstable_v1" or "wlr_virtual_pointer_unstable_v1", both
of which allow the user to select a seat.
The "wl_seat" global created by this protocol does not generate input events
on its own, or have any capabilities except those assigned to it by other
protocol extensions, such as the ones mentioned above.
For example, a remote desktop server can create a seat with virtual inputs
for each remote user by following these steps for each new connection:
* Create a transient seat
* Wait for the transient seat to be created
* Locate a "wl_seat" global with a matching name
* Create virtual inputs using the resulting "wl_seat" global
