[MPlayer-dev-eng] [PATCH] mousewheel support for vo_sdl.c

[Wojtek Kaniewski]

it's a simple and probably stupid patch which allows seeking with
mousewheel. with no buttons pressed while moving the wheel, it seeks
+/- 1 minute, with left button pressed +/- 10 seconds, with right
button +/- 10 minutes and with mousewheel pressed it changes the
volume.

btw, there's no information how to signup for mplayer-dev-eng in
DOCS/tech/patches.txt. it can be a little confusing :/

regards,
wojtek
