Re: [AD] Windows mouse (patch)

[Javier González <xaviergonz@xxxxxxxxxx>]

Ok, attached is a new patch and this is what it does:
  if the relative movement of the x axis is > than 32, it multiplies the
movement in
that axis * 4
if it's > 16, it multiplies the movement * 2
the same for y axis

that way we get a mouse with two treshold values working (and works like the
windows cursor now) but using directinput, and with setspeed working

what do you think of this one? Eric? George?

Thanks in advance
