1094 * doesn't get expose events so we don't get to use our true back-buffer,
1095 * wasting memory and performance (this is valid for both d3d and gdi
1096 * pipelines)
1097 * - in some cases with buffer per window enabled it is possible for the
1098 * paint manager to redirect rendering to the screen for some operations
1099 * (like copyArea), and since bpw uses its own BufferStrategy the
1100 * d3d onscreen rendering support is disabled and rendering goes through
1101 * GDI. This doesn't work well with Vista's DWM since one
1102 * can not perform GDI and D3D operations on the same surface
1103 * (see 6630702 for more info)
1104 *
1105 * Note: even though DWM composition state can change during the lifetime
1106 * of the application it is a rare event, and it is more often that it
1107 * is temporarily disabled (because of some app) than it is getting
1108 * permanently enabled so we can live with this approach without the
