/* About VK_IMAGE_LAYOUT_PRESENT_SRC_KHR, the spec says
 *
 *    VK_IMAGE_LAYOUT_PRESENT_SRC_KHR must only be used for presenting a
 *    presentable image for display. A swapchain's image must be transitioned
 *    to this layout before calling vkQueuePresentKHR, and must be
 *    transitioned away from this layout after calling vkAcquireNextImageKHR.
 *
 * That allows us to treat the layout internally as
 *
 *  - VK_IMAGE_LAYOUT_GENERAL
 *  - VK_QUEUE_FAMILY_FOREIGN_EXT has the ownership, if the image is not a
 *    prime blit source
 *
 * while staying performant.
 *
 * About queue family ownerships, the spec says
 *
 *    A queue family can take ownership of an image subresource or buffer
 *    range of a resource created with VK_SHARING_MODE_EXCLUSIVE, without an
 *    ownership transfer, in the same way as for a resource that was just
 *    created; however, taking ownership in this way has the effect that the
 *    contents of the image subresource or buffer range are undefined.
 *
 * It is unclear if that is applicable to external resources, which supposedly
 * have the same semantics
 *
 *    Binding a resource to a memory object shared between multiple Vulkan
 *    instances or other APIs does not change the ownership of the underlying
 *    memory. The first entity to access the resource implicitly acquires
 *    ownership. Accessing a resource backed by memory that is owned by a
 *    particular instance or API has the same semantics as accessing a
 *    VK_SHARING_MODE_EXCLUSIVE resource[...]
 *
 * We should get the spec clarified, or get rid of this completely broken code
 * (TODO).
 *
 * Assuming a queue family can acquire the ownership implicitly when the
 * contents are not needed, we do not need to worry about
 * VK_IMAGE_LAYOUT_UNDEFINED.  We can use VK_IMAGE_LAYOUT_PRESENT_SRC_KHR as
 * the sole signal to trigger queue family ownership transfers.
 *
 * When the image has VK_SHARING_MODE_CONCURRENT, we can, and are required to,
 * use VK_QUEUE_FAMILY_IGNORED as the other queue family whether we are
 * transitioning to or from VK_IMAGE_LAYOUT_PRESENT_SRC_KHR.
 *
 * When the image has VK_SHARING_MODE_EXCLUSIVE, we have to work out who the
 * other queue family is.  It is easier when the barrier does not also define
 * a queue family ownership transfer (i.e., srcQueueFamilyIndex equals to
 * dstQueueFamilyIndex).  The other queue family must be the queue family the
 * command buffer was allocated for.
 *
 * When the barrier also defines a queue family ownership transfer, it is
 * submitted both to the source queue family to release the ownership and to
 * the destination queue family to acquire the ownership.  Depending on
 * whether the barrier transitions to or from VK_IMAGE_LAYOUT_PRESENT_SRC_KHR,
 * we are only interested in the ownership release or acquire respectively and
 * should be careful to avoid double releases/acquires.
 *
 * I haven't followed all transition paths mentally to verify the correctness.
 * I likely also violate some VUs or miss some cases below.  They are
 * hopefully fixable and are left as TODOs.
