1048 * There are two reasons why we don't use buffer per window when

1050 * - since with DWM all windows are already double-buffered, the application
1051 * doesn't get expose events so we don't get to use our true back-buffer,
1052 * wasting memory and performance (this is valid for both d3d and gdi
1053 * pipelines)
1054 * - in some cases with buffer per window enabled it is possible for the
1055 * paint manager to redirect rendering to the screen for some operations
1056 * (like copyArea), and since bpw uses its own BufferStrategy the
1057 * d3d onscreen rendering support is disabled and rendering goes through
1058 * GDI. This doesn't work well with Vista's DWM since one
1059 * can not perform GDI and D3D operations on the same surface
1060 * (see 6630702 for more info)
1061 *
1062 * Note: even though DWM composition state can change during the lifetime
1063 * of the application it is a rare event, and it is more often that it
1064 * is temporarily disabled (because of some app) than it is getting
1065 * permanently enabled so we can live with this approach without the
1066 * complexity of dwm state listeners and such. This can be revisited if
