Pointer glide idea for Synaptics driver

[Dylan McCall]

It isn't /required/ to use synclient and SHMConfig; one can use the
configuration in xorg.conf if he wants. For temporary fiddling,
though, synclient is a nice and simple way to get the friction
settings just right.

The patch is a bit troublesome because some of it is in a list of
variables that loves to change. Shouldn't be too tough to copy and
paste it manually, since it's very little code for now.

Thanks for making that package, Siegfried. Hope nobody's system explodes! :)
