NEWT: Add EventDispatchThread (EDT) pattern.
Due to limitations on Windows, we need to standardize the one thread for - window creation, and - event dispatching This was already mentioned in the previous implementation but while integrating into another threading model (Plugin3), it turned out that manual managing the thread is too much of a burden. NEWT now uses a EDT per Display and Thread as the default, where Display creation, Window creation and event dispatching is 'pipelined' into. This can be switched off: NewtFactory.setUseEDT(boolean onoff); and queried via: NewtFactory.useEDT(); Note this EDT impl. does not implicate a global lock or whatsoever. The experimantal semantics of a current GL context for input event dispatching is removed, i.e. the GL context is no more made current for mouse/key listener. This reduces the complexity and allows the proper impl. of the external dispatch via EDT .. for example. Removed: GLWindow: setEventHandlerMode(int) .. etc X11Display: XLockDisplay/XUnlockDisplay needed to be utilized to allow the new multithreading (EDT/Render) Display usage. X11Window: lockSurface/unlockSurface locks X11Display as well .. +++++ NEWT: 'getSurfaceHandle()' semantics changed. To allow usage of the surfaceHandle for OS where it is allocated thread local (MS-Windows), it shall be aquired/released while lockSurface/unlockSurface. This is done in the Windows Window implementation. GLWindow can no more query 'getSurfaceHandle()' to verify if 'setRealized()' was successful. NEWT: Window surface lock is recursive and blocking now, as it shall be.
