Previously, "dar" and "a" were documented like "input display aspect ratio", but their actual value was "in_w/in_h". In order to avoid to break scripts which rely on the "a" variable, the patch keeps the same semantics but fixes the corresponding docs, and fixes the semantics of the recently added "dar" variable, which now correctly expresses the input Display Aspect Ratio value as "(inw_w/in_h)*sar".
