描述
In this page:
https://docs.vulkan.org/tutorial/latest/Building_a_Simple_Engine/Engine_Architecture/05_rendering_pipeline.html#_rendergraph_dependency_analysis_and_execution_ordering
It's doing
```
for (auto dependent : dependents[node]) {
visit(dependent);
}
```
However doesn't that mean that the dependents will be executed first, before the pass that they depend on has executed. Shouldn't this be looping on `dependencies`?

调研方向
Read the RenderGraph dependency analysis and execution ordering section at the linked documentation page, focusing on the shown loop over dependents. Trace the dependency direction and execution-order explanation to determine whether the example is reversed; done means the code and accompanying text consistently describe the correct ordering.
