* .dstSubpass = firstSubpass; // First subpass attachment is used in

* .dependencyFlags = 0;
* };
*
* Similarly, if there is no subpass dependency from the last subpass
* that uses an attachment to VK_SUBPASS_EXTERNAL, then an implicit
* subpass dependency exists from the last subpass it is used in to
* VK_SUBPASS_EXTERNAL. The subpass dependency operates as if defined
* with the following parameters:
*
* VkSubpassDependency implicitDependency = {
* .srcSubpass = lastSubpass; // Last subpass attachment is used in
* .dstSubpass = VK_SUBPASS_EXTERNAL;

* VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
* .dstAccessMask = 0;
* .dependencyFlags = 0;

*
* We could implement this by walking over all of the attachments and

* dependency. Or, we could just be lazy and add a couple extra flushes.
