| fence | 指示 GPU 在执行图形队列处理前等待的 GPUFence。 |
| stage | 在某些平台中，对于特定的绘制调用，在完成顶点处理和开始像素处理之间存在明显间隙。此参数允许请求的等待在下一个项目顶点或像素处理开始之前。如果下一个要提交的项目是计算着色器分发，此参数将被忽略。 |
指示 GPU 图形队列处理等待传递给定的 GPUFence。
有些平台无法区分顶点和像素处理的开始，这些平台在下一个项目顶点处理开始之前将一直等待，而不考虑传递给 stage 参数的值。
在不支持 GPUFence 的平台中，该调用不执行任何操作，请参阅 SystemInfo.supportsGPUFence。
用户在使用该函数时可能会造成 GPU 死锁。应注意确保在指示 GPU 等待之前能够完成传递的 GPUFence。
此函数将立即在 CPU 中返回，栅栏将只影响 GPU 处理。
另请参阅：GPUFence、Graphics.CreateGPUFence。
