--- Get the duplicate of a cairo surface
--- Create a copy of a cairo surface.
-- The surfaces returned by `surface.load` are cached and must not be
-- modified to avoid unintended side-effects. This function allows to create
-- a copy of a cairo surface. This copy can then be freely modified.
-- The surface returned will be as compatible as possible to the input
-- surface. For example, it will likely be of the same surface type as the
-- input. The details are explained in the `create_similar` function on a cairo
-- surface.
-- @param s Source surface.
-- @return The surface's duplicate.
