Add ass_set_storage_size and fix related scaling issues
\blur radius is not scaled from script to storage resolution
but is scaled from storage to display resolution. The same
applies to borders and shadows if ScaledBorderAndShadow is "no".
(If it is "yes", borders and shadows are scaled from script
to display resolution just like before.)
