Uniquely labels an image
This is host set and allows a plug-in to differentiate between images. This is especially useful if a plugin caches analysed information about the image (for example motion vectors). The plugin can label the cached information with this identifier. If a user connects a different clip to the analysed input, or the image has changed in some way then the plugin can detect this via an identifier change and re-evaluate the cached information.
