vkTransitionImageLayout

To perform an image layout transition on the host, call:

VkResult vkTransitionImageLayoutEXT(
    VkDevice device,
    uint32_t transitionCount,
    const VkHostImageLayoutTransitionInfo*    pTransitions);

• device is the device which owns pTransitions[i].image.
• transitionCount is the number of image layout transitions to perform.
• pTransitions is a pointer to an array of VkHostImageLayoutTransitionInfo structures specifying the image and subresource ranges within them to transition.
