256 * Similarly, if there is no subpass dependency from the last subpass
257 * that uses an attachment to VK_SUBPASS_EXTERNAL, then an implicit
258 * subpass dependency exists from the last subpass it is used in to
259 * VK_SUBPASS_EXTERNAL. The subpass dependency operates as if defined

262 * VkSubpassDependency implicitDependency = {

271 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
272 * .dstAccessMask = 0;
273 * .dependencyFlags = 0;
276 * We could implement this by walking over all of the attachments and
277 * subpasses and checking to see if any of them don't have an external
278 * dependency. Or, we could just be lazy and add a couple extra flushes.
279 * We choose to be lazy.
