We need to provide a way to choose v-synced BufferStrategy enabled by the fix for 6678218 [D3D: provide a way to create a v-synced BufferStrategy]
This is required for smooth animation for FX.
We want to mark top level components with vsynced requested bit and
then create vsynced BufferStrategy for them in BufferStrategyPaintManager.
Two things to note here:
First swing does not always use BufferStrategyPaintManager.
Second java2d can not guarantee vsynced BufferStrategy even if we request one.
That means that even if vsynced painting is requested for a top level
we might not get one.
