/// Width and height of a layer surface in pixels
///
/// According to the Wayland wlr-layer-shell protocol:
/// - Pass 0 for either width or height to have the compositor assign it
/// - The compositor will center the surface with respect to its anchors
/// - When using 0, you MUST anchor to opposite edges in that dimension:
///   - width = 0 requires both left and right anchors
///   - height = 0 requires both top and bottom anchors
/// - Not following this requirement is a protocol error
/// - Both values default to 0
///
/// Size is double-buffered via `wl_surface.commit`.
