    \ingroup qpa

    \brief The QPlatformVulkanInstance class provides an abstraction for Vulkan instances.

    The platform Vulkan instance is responsible for loading a Vulkan library,
    resolving the basic entry points for creating instances, providing support
    for creating new or adopting existing VkInstances, and abstracting some
    WSI-specifics like checking if a given queue family can be used to present
    using a given window.

    \note platform plugins will typically subclass not this class, but rather
    QBasicVulkanPlatformInstance.

    \note Vulkan instance creation is split into two phases: a new
    QPlatformVulkanInstance is expected to load the Vulkan library and do basic
    initialization, after which the supported layers and extensions can be
    queried. Everything else is deferred into createOrAdoptInstance().
