[MPlayer-dev-eng] [PATCH] really clear vidix on start

[Reimar Döffinger]

Hello,
currently the vidix vos upon startup only clear the frame to grey
instead of black. It seems (from what I guess from a user report) that
in case of ATI cards it doesn't get cleared at all currently??
It is best to see when playing a video with -fps 1.
Attached patch should fix it.
Please comment, I will apply soon.

Greetings,
Reimar Döffinger
