| #define NV2_LABEL_PROTOCOL_VERSION ((uint32_t) 2004) |
Represents the current version of struct nv2_patch_label.

| #define NV2_MAX_LABEL_CONFIDENCE 10000u |
The scaling factor used to represent confidence levels in nv2_patch_label.
A raw confidence value in [0,1] should be encoded as uint32_t(0.5 + raw*NV2_MAX_LABEL_CONFIDENCE)
