// For each sharer in the conference, we remember the last shared list
// they sent us--the HWNDs (on their machine, no meaning on ours), the
// state information, and the position.
//
// We use this for several purposes:
// (1) 2.x compatibility
// 2.x sharers, when they send SWL lists, do not fill in the position
// of shadows representing other remote app windows. Those will appear
// in the list if they obscure parts of shared windows on the 2.x host. The
// old 2.x code would look up the last position info in the global shared
// list, and use that. We need the position info to accurately compute
// the obscured regions for a particular host. 3.0 sharers don't have
// shadows, they never send incomplete info.
//
// (2) For better UI in the host view
// We can remember where the window on top is, where the active window
// is (if a 3.0 host), if a window is minimized, etc. Since we don't have
// independent fake windows floating with tray buttons you can manipulate
// on a remote to manipulate the host, minimized windows will disappear.
// Only Alt-Tabbing (when controlling) can activate and restore them.
