<description summary="screen content capturing on client buffers">
This protocol allows clients to ask the compositor to copy part of the
screen content to a client buffer.
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="a frame ready for copy">
This object represents a single frame.
When created, a series of buffer events will be sent, each representing a
supported buffer type. The "buffer_done" event is sent afterwards to
indicate that all supported buffer types have been enumerated. The client
will then be able to send a "copy" request. If the capture is successful,
the compositor will send a "flags" followed by a "ready" event.
For objects version 2 or lower, wl_shm buffers are always supported, ie.
the "buffer" event is guaranteed to be sent.
If the capture failed, the "failed" event is sent. This can happen anytime
before the "ready" event.
Once either a "ready" or a "failed" event is received, the client should
destroy the frame.

<description summary="indicates frame is available for reading">
Called as soon as the frame is copied, indicating it is available
for reading. This event includes the time at which presentation happened
at.
The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples,
each component being an unsigned 32-bit value. Whole seconds are in
tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo,
and the additional fractional part in tv_nsec as nanoseconds. Hence,
for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part
may have an arbitrary offset at start.
After receiving this event, the client should destroy the object.
