// words, "by design." apparently the designers of windows 2000
// we're a little less lazy and did it right.
//
// microsoft recommends in Q193003 to absolute position the cursor
// somewhere on the primary monitor then relative move to the
// desired location. this doesn't work for us because when the
// user drags a scrollbar, a window, etc. it causes the dragged
// item to jump back a forth between the position on the primary
// monitor and the desired position. while it always ends up in
// the right place, the effect is disconcerting.
//
// instead we'll get the cursor's current position and do just a
// relative move from there to the desired position. relative
// moves are subject to cursor acceleration which we don't want.
// so we disable acceleration, do the relative move, then restore
// acceleration. there's a slight chance we'll end up in the
// wrong place if the user moves the cursor using this system's
// mouse while simultaneously moving the mouse on the server
// system. that defeats the purpose of synergy so we'll assume
// that won't happen. even if it does, the next mouse move will
