/**
 * @page page_vsync_feedback_unstable_v1 The vsync_feedback_unstable_v1 protocol
 * Protocol for providing vertical synchronization timing
 *
 * @section page_desc_vsync_feedback_unstable_v1 Description
 *
 * This protocol specifies a set of interfaces used to inform the client about
 * vertical synchronization timing in a precise way and without unnecessary
 * overhead.
 *
 * 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 version number in the protocol is removed and
 * the interface version number is reset.
