Determines if objects are sorted, and how. Sorting is done level by level (and not for all entities), values are :

osInherited : use inherited sorting mode, defaults to osRenderFarthestFirst

osNone : do not sort objects.

osRenderFarthestFirst : render objects whose Position is the farthest from the camera first.

osRenderBlendedLast : opaque objects are not sorted and rendered first, blended ones are rendered afterwards and depth sorted.

osRenderNearestFirst : render objects whose Position is the nearest to the camera first.

TGLObjectsSorting = (osInherited,osNone,osRenderFarthestFirst,osRenderBlendedLast,osRenderNearestFirst);
