The special queue family index
any queue external to the resource’s current Vulkan instance, regardless of
the queue’s underlying physical device or driver version.
This includes, for example, queues for fixed-function image processing
devices, media codec devices, and display devices, as well as all queues
that use the same underlying
device group or
physical device, and the same driver version as the resource’s
