| * dependency exists from VK_SUBPASS_EXTERNAL to the first subpass it is |
| * used in. The subpass dependency operates as if defined with the |
| * following parameters: |
| * |
| * VkSubpassDependency implicitDependency = { |
| * .srcSubpass = VK_SUBPASS_EXTERNAL; |
| * .dstSubpass = firstSubpass; // First subpass attachment is used in |
| * .srcStageMask = VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT; |

| * .srcAccessMask = 0; |
| * .dstAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT | |
| * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT | |

| * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT | |
| * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT; |
| * .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; |
| * .srcStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT; |
| * .dstStageMask = VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT; |
| * .srcAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT | |
| * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT | |
| * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT | |
| * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT | |
| * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT; |
| * .dstAccessMask = 0; |
| * .dependencyFlags = 0; |
| * }; |
| * |
| * We could implement this by walking over all of the attachments and |
| * subpasses and checking to see if any of them don't have an external |
| * dependency. Or, we could just be lazy and add a couple extra flushes. |
| * We choose to be lazy. |
