[MPlayer-dev-eng] mga_vid.c fix (!?)

[Michael Lampe]

The original mga_vid.c corrupts the mouse pointer on my system (XFree
4.1.0, G400 32M SGRAM) while playback. Lowering mga_src_base by 1K
helps. Of course, I don't understand anything from this stuff, but that
it steals memory from the X xerver without making him aware. My guess is
that the pixmap for the hardware cursor is on the upper end.
