Optical Flow
Optical Flow Queues
VK_NV_optical_flow adds an optical flow queue type bit
VK_QUEUE_OPTICAL_FLOW_BIT_NV to VkQueueFlagBits.
Optical flow operations are supported by queues with an advertised queue
capability of VK_QUEUE_OPTICAL_FLOW_BIT_NV.
As in the case of other queue types, an application must use
vkGetPhysicalDeviceQueueFamilyProperties to query whether the physical
device has support for the Optical Flow Queue.
When the implementation reports the VK_QUEUE_OPTICAL_FLOW_BIT_NV bit
for a queue family, it advertises general support for Vulkan queue
operations described in Devices and Queues.
