This function sets the "base file" of the handle to be file itself, so SVG
elements like <image> which reference external
resources will be resolved relative to the location of file.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the
operation was cancelled, the error gio.types.IOErrorEnum.Cancelled will be
returned in error.
