<description summary="control data devices">
This protocol allows a privileged client to control data devices. In
particular, the client will be able to manage the current selection and take
the role of a clipboard manager.
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.

A wlr_data_control_offer represents a piece of data offered for transfer

MIME types that the data can be converted to and provides the mechanism
for transferring the data directly from the source client.
</description>

<description summary="request that the data is transferred">
To transfer the offered data, the client issues this request and
indicates the MIME type it wants to receive. The transfer happens
through the passed file descriptor (typically created with the pipe
system call). The source client writes the data in the MIME type
representation requested and then closes the file descriptor.
The receiving client reads from the read end of the pipe until EOF and
then closes its end, at which point the transfer is complete.
This request may happen multiple times for different MIME types.
