ASS subtitle is stretched according to PAR
ASS subtitle is stretched when it is displayed over a video whose PAR is not 1:1.
For example, if the display size is 640x480 and the storage size is 320x480, PAR is 2:1 and the subtitle text is stretched horizontally (= larger width than expected). The position of the head of the subtitle text is same as those in case of PAR is 1:1.
