DtTerrainSourcePager is the base class for terrain pagers. There will be one terrainSourcePager per terrain patch. They will each handle paging in terrain from an individual source, such as metaflight, paged .ive, or osgEarth streaming terrain.

virtual

Takes incoming commands off the command queue and adds them to the priority-sorted command map.

Thread-safe queue to put commands on.

DtCommandPriorityMultimap DtTerrainSourcePager::myPriorityCommandMultimap
