-* FTServer FTServer is the Class, that communicates headpose-data *
-* to games, using the FreeTrackClient.dll. *
-* It was (very) loosely translated from FTServer.pas. *
-* which was created by the FreeTrack-team. *

-// There are some issues, that may need solving:
-//
-// The FaceAPI only runs in the 'Release' configuration. It may have something to
-// do with compiler-settings, but for now it's not solved...
-// --> WVR 20101023: This was solved by downgrading to VS2005...
-//
-// Connecting with the Freetrack DLL only seems to work, when UNICODE is OFF.
-// That's strange, isn't it?
-// --> WVR 20100409: Update on this: Loading the DLL with QLibrary implemented.
-// With UNICODE on, the DLL is loaded fine, but the memory-mapping
-// does not. Explicitely using the 'A' extension for CreateFileMapping
-// solves this (for now.) Maybe there is a Qt substitute for this?
-//
-/*
- Modifications (last one on top):
- 20101224 - WVR: Base class is no longer inheriting QThread. sendHeadposeToGame
- is called from run() of Tracker.cpp
- 20100601 - WVR: Added Mutex-bit in run(). Thought it wasn't so important (still do...).
- 20100523 - WVR: Implemented the Freetrack-protocol just like Freetrack does. Earlier
- FaceTrackNoIR only worked with an adapted DLL, with a putdata function.
- Now it works direcly in shared memory!
