// created must support at least one graphics queue, which is passed in as well.
// The QueueFamilyIndex must match the family of the given queue. It is needed for CommandPool
// creation, and any GrBackendObjects handed to us (e.g., for wrapped textures) needs to be created
// in or transitioned to that family. The refs held by members of this struct must be released
// (either by deleting the struct or manually releasing the refs) before the underlying vulkan
// device and instance are destroyed.
