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. * * @section page_ifaces_alpha_compositing_unstable_v1 Interfaces * - @subpage page_iface_zcr_alpha_compositing_v1 - alpha_compositing * - @subpage page_iface_zcr_blending_v1 - blending interface to a wl_surface * @section page_copyright_alpha_compositing_unstable_v1 Copyright * <pre> * * Copyright 2016 The Chromium Authors * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice (including the next * paragraph) shall be included in all copies or substantial portions of the * Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
