Hi,
If the only argument for adding GGI is so that you don't have to install
libsdl, then does that mean that we should have an X11, fbdev, etc.
backend for people who don't have GGI installed?
I think a GGI back-end would be useful.
I wouldn't mind also having other back-ends even if SDL supports them
(e.g. there's an Xlib patch for qemu, it is very little code compared
to vnc.c which you could say duplicates code already present in
libraries). The situation is the same with audio backends: there's
oss, alsa and SDL which can do both oss and alsa but works poorly.
Unrelated to this discussion on slow links VNC is much more usable
with the Xlib patch and Xvnc than through the built-in VNC (I think it
makes a better decision on what format to use based on the connection
speed).
