* An allocator is responsible for allocating memory for pixel buffers.
*
* Each allocator may return buffers with different capabilities (shared
* memory, DMA-BUF, memory mapping, etc), placement (main memory, VRAM on a
* GPU, etc) and properties (possible usage, access performance, etc). See
* struct wlr_buffer.
*
* An allocator can be passed to a struct wlr_swapchain for multiple buffering.
