1072 * - since with DWM all windows are already double-buffered, the application
1073 * doesn't get expose events so we don't get to use our true back-buffer,
1074 * wasting memory and performance (this is valid for both d3d and gdi
1075 * pipelines)
1076 * - in some cases with buffer per window enabled it is possible for the
1077 * paint manager to redirect rendering to the screen for some operations
1078 * (like copyArea), and since bpw uses its own BufferStrategy the
1079 * d3d onscreen rendering support is disabled and rendering goes through
1080 * GDI. This doesn't work well with Vista's DWM since one
1081 * can not perform GDI and D3D operations on the same surface
1082 * (see 6630702 for more info)
1083 *
1084 * Note: even though DWM composition state can change during the lifetime
1085 * of the application it is a rare event, and it is more often that it
1086 * is temporarily disabled (because of some app) than it is getting
1087 * permanently enabled so we can live with this approach without the
