[MPlayer-dev-eng] [PATCH] libass - fix text aspect w/ panscan and vo_gl

[Jindrich Makovicka]

Hi,

libass currently does not account for the areas cropped by pan/scan,
which causes text deformation when zooming a widescreen movie.

The attached patch fixes this issue by modifying the semantics of
ass_set_margins(). It now allows negative values, which are interpreted
as cropping offsets, and are later used in the aspect ration
calculation.

Regards,
