[MPlayer-dev-eng] [PATCH] allow highly experimental negative panscan values

[Reimar D?ffinger]

Hello,
what do you think about attached patch? It allows to "zoom out" with
some vos (gl works almost fine except that for too large values it flips
the video, xv crashes or gives errors with too large but works mostly,
breaks switching out of fullscreen for gl2, others not tested).

Greetings,
Reimar Döffinger
