[MPlayer-dev-eng] [PATCH] ggi osd support corrected, and page flipping added

[spdepagn at ncsu.edu]

Hi, I corrected the osd code so it does the correct thing without memory
poking.

I also noticed shearing effects when watching movies with fast action, so
I added support so ggi creates two video frames and implements page
flipping.  If ggi cannot allocate two full frames, it defaults to one
frame.  I tested this and the shearing effects are gone.  I tested
allocation by allocating more pages than my video card supported to make
sure it caught this.

I also added support for the keys 1, 2, 3, 4 so that brightness and
contrast can be adjusted.

I tried to create the patch from a level so you can use
patch < mplayer_ggi.patch

thanks,
Sean D'Epagnier
