It also sets an event listener. this has to be informed of
mouse and keys events within the view component by implementations
of this method.

protected abstract void invokeRender(int flags)
run() in this ViewComponent's own thread.
Its sole task is to invoke invokeRenderSync(int) in
the rendering thread (which may be this
ViewComponent's thread, the AWT-thread, or another
thread, depending on the implementation) in a write-protected
context. The invocation has to be
synchronously, i.e., if it is in another thread, the current thread
has to wait until invokeRenderSync(int) has completed.
flags - the flags to pass to invokeRenderSync(int)protected void invokeRenderSync(int flags)
render(int), ensuring that
Workbench.current() returns the correct workbench.
If render(int) throws an InterruptedException,
a repaint is posted. The write-lock of this view's graph has to be
acquired by the invoker (see Lockable).
