Send VD_AGENT_SEAMLESS_MODE_CHANGE message to client instead of the whole
list of windows. The message contains VDAgentSeamlessModeWindow struct with
window's coordinates and its id (HWND). Zero width indicates the window is
not visible anymore.
This improves performance as the agent doesn't have to cycle through all the
windows.
