EVALUATION
Java2D will provide a way to create v-synch-ed buffer strategies
when the d3d pipeline is enabled.
Note that since the D3D pipeline uses single thread rendering - meainng
that all D3D-related activity happens on a single thread only
one BufferStrategy in per vm instance can be made v-synced without
undesireable effects.
If there's more than one (say N) v-synced BSs then
since their Present() calls will effectively be serialized (since they're
running from a single thread) each BS will be able
to flip only on every Nth vsync, resulting in decrease in
perceived responsiveness.
Additional work will be needed in Swing to use this internal
API to create a v-synced swing back-buffer at Scenario's request,
this will be tracked by a different bug.
