[MPlayer-dev-eng] [PATCH] vo_tdfxfb.c clear screen and tiny image bug

[Burton Samograd]

Here's a quick little patch i did that *might* work.  It moves the
buffer pointers from the beginning of screen memory (where the conole
lives) to right after it.  This worked with the tdfxfb driver...of
course it could totally screw everything up since i don't have a card
to test it on :)  I only changed a couple of lines and the old code is
just #if 0'd out so you can change it back really easily.
