* is called is the message pumping thread. Violating this assumption

*
* embeddedInit must be called before the WToolkit() constructor.
* embeddedDispose should be called before the applicaton terminates the
* Java VM. It is currently unsafe to reinitialize the toolkit again
* after it has been disposed. Instead, awt.dll must be reloaded and the
* class loader which loaded WToolkit must be finalized before it is
* safe to reuse AWT. Dynamic reusability may be added to the toolkit in

* wasting memory and performance (this is valid for both d3d and gdi
* pipelines)
* - in some cases with buffer per window enabled it is possible for the
* paint manager to redirect rendering to the screen for some operations
* (like copyArea), and since bpw uses its own BufferStrategy the
* d3d onscreen rendering support is disabled and rendering goes through
* GDI. This doesn't work well with Vista's DWM since one
* can not perform GDI and D3D operations on the same surface
* (see 6630702 for more info)
*
* Note: even though DWM composition state can change during the lifetime
* of the application it is a rare event, and it is more often that it
* is temporarily disabled (because of some app) than it is getting
* permanently enabled so we can live with this approach without the
* complexity of dwm state listeners and such. This can be revisited if
