Functions
std::optional< uint32_t >	exported_record_count (const std::shared_ptr< Portal::Graphics::GpuBufferHandle > &handle, size_t stride_vec4)
	Clamped record count from an exported buffer's vec4 header, or nullopt when the buffer isn't readable.
PixelRect	region_rect (const std::optional< Kinesis::Vision::BoundingBox > &region, uint32_t w, uint32_t h)
	Pixel rectangle of a normalised region over a w x h image, clamped to the image.

Variables
constexpr uint32_t	CC_BACKGROUND_HOST = 0xFFFFFFFFU
constexpr uint32_t	CC_UNCLAIMED_HOST = 0U
constexpr size_t	k_flow_args_count = 4
constexpr uint64_t	k_flow_args_stride = 3 * sizeof(uint32_t)
constexpr uint32_t	k_flow_dense_max_radius = 15
	Largest summation window radius of the dense solver.
constexpr uint32_t	k_flow_duplicate_energy = 16
	Frame change, in 1/1024 intensity summed over pixels, at or below which a frame counts as a repeat.
constexpr size_t	k_flow_export_vec4 = size_t { 1 } + size_t { k_flow_max_points } * 2
	Export buffer size in vec4: one header plus two per track.
