/**
 * Load a 3D model with or without XML wrapper.  This version supports
 * also loading the instrument panel and is wired in with dependencies
 * on panelnode.hxx, and thus files in src/Cockpit and also GUI/mouse
 * input code to support the 3d clickable hotspots.
 *
 * If the path ends in ".xml", then it will be used as a property-
 * list wrapper to add animations to the model.
 *
 * Subsystems should not normally invoke this function directly;
 * instead, they should use the SGModelLoader declared in loader.hxx.
