/**
* SECTION:meta-wayland-buffer
* @title: MetaWaylandBuffer
* @short_description: A wrapper for wayland buffers
*
* #MetaWaylandBuffer is a general wrapper around wl_buffer, the basic way of
* passing rendered data from Wayland clients to the compositor. Note that a
* buffer can be backed by several types of memory, as specified by
* #MetaWaylandBufferType.
*/
/**
* MetaWaylandBufferType:
* @META_WAYLAND_BUFFER_TYPE_UNKNOWN: Unknown type.
* @META_WAYLAND_BUFFER_TYPE_SHM: wl_buffer backed by shared memory
* @META_WAYLAND_BUFFER_TYPE_EGL_IMAGE: wl_buffer backed by an EGLImage
* @META_WAYLAND_BUFFER_TYPE_EGL_STREAM: wl_buffer backed by an EGLStream (NVIDIA-specific)
* @META_WAYLAND_BUFFER_TYPE_DMA_BUF: wl_buffer backed by a Linux DMA-BUF
*
* Specifies the backing memory for a #MetaWaylandBuffer. Depending on the type
* of buffer, this will lead to different handling for the compositor. For
* example, a shared-memory buffer will still need to be uploaded to the GPU.
