mpv/libvo/vo_gl.c
eugeni 92efd606d1 Avoid text deformation and subtitles moving outside the screen in pan-and-scan 
mode.

For this, crop amounts are passed from vo_gl as negative margins sizes. They
are used to calculate aspect ratio. They are ignored when calculating subtitle
 positions, so subtitles will stay on screen most of the time.
Based on a patch by Jindrich Makovicka [makovick gmail com].
