812 *
813 * In most cases d3d->screen copy happens only during some transitional

815 * restored (for example, when Swing's backbuffer VI is copied to the screen
816 * but the D3DScreenSurfaceManager couldn't restore its surface).
817 *
818 * An exception is if for some reason we could not enable accelerated on-screen
819 * rendering for this window for some permanent reason (like window being too
820 * small, or a present BufferStrategy).
821 *
822 * This meant that we'd disable hw acceleration after the first failure
823 * completely (at least until the src image is recreated which in case of
824 * Swing back-buffer happens only after resize).
825 *
826 * Now we delegate to the VISM to figure out if the acceleration needs to
827 * be disabled or if we can wait for a while until the onscreen accelerated
828 * can resume (by marking the source surface lost and making sure the
829 * VISM has a chance to use the backup surface).
