Subject: libretro: call video_cb on every frame
X-Git-Tag: r18~49^2~5

libretro: call video_cb on every frame

We need to do video_cb in retro_run every frame instead of
just once every time the video callback is called - otherwise
we will get very bad/skippy framerates.
Performance is much improved now in nearly all games.
