What's the preferred method of loading a model, for example an open flight model, and pruning it of unneeded data? I assume that would be by making a custom visitor that modifies the hierarchy. Is that correct?
How would you do this with respect to the pager? I don't see a mechanism to inject a custom visitor to the pager to modify loaded content, ideally before caching to the file cache. I'm inclined to add a custom visitor pointer to the options class like a "postLoad" to post process the models in a way that is compatible with the pager and file caching. Does that seem reasonable? Did I miss any alternative methods?
