    Gets a temporary path and agrees to remove on close.

    This implementation does not use tempfile.mkstemp to avoid having a file handle.
    If the code using the returned path wants to delete the file itself, windows
    requires that no program has a file handle to it.

    Parameters
    ----------
    filename : str (optional)
        suffix of the created file.
    return_filelike : bool (default False)
        if True, returns a file-like which is *always* cleaned. Necessary for
        savefig and other functions which want to append extensions.
    **kwargs
        Additional keywords are passed to open().
