Detailed Description

Allocates and hands out std::shared_ptr<QueueHandle> instances for thread-safe access to Vulkan Queues.

Each QueueWrapper represents a single Vulkan Queue. Many pointers to a single QueueWrapper, each with its own QueueHandle, may exist at a given time, e.g. if the GPU only provides a single queue of the required type.
