1078 * doesn't get expose events so we don't get to use our true back-buffer,
1079 * wasting memory and performance (this is valid for both d3d and gdi
1080 * pipelines)
1081 * - in some cases with buffer per window enabled it is possible for the
1082 * paint manager to redirect rendering to the screen for some operations
1083 * (like copyArea), and since bpw uses its own BufferStrategy the
1084 * d3d onscreen rendering support is disabled and rendering goes through
1085 * GDI. This doesn't work well with Vista's DWM since one
1086 * can not perform GDI and D3D operations on the same surface
1087 * (see 6630702 for more info)
1088 *
1089 * Note: even though DWM composition state can change during the lifetime
1090 * of the application it is a rare event, and it is more often that it
1091 * is temporarily disabled (because of some app) than it is getting
1092 * permanently enabled so we can live with this approach without the
