示例1: handleVItoScreenOp

import sun.java2d.windows.GDIWindowSurfaceData; //导入方法依赖的package包/类
/**
 * If the destination surface's peer can potentially handle accelerated
 * on-screen rendering then it is likely that the condition which resulted
 * in VI to Screen operation is temporary, so this method sets the
 * restore countdown in hope that the on-screen accelerated rendering will
 * resume. In the meantime the backup surface of the VISM will be used.
 *
 * The countdown is needed because otherwise we may never break out
 * of "do { vi.validate()..} while(vi.lost)" loop since validate() could
 * restore the source surface every time and it will get lost again on the
 * next copy attempt, and we would never get a chance to use the backup
 * surface. By using the countdown we allow the backup surface to be used
 * while the screen surface gets sorted out, or if it for some reason can
 * never be restored.
 *
 * If the destination surface's peer could never do accelerated onscreen
 * rendering then the acceleration for the SurfaceManager associated with
 * the source surface is disabled forever.
