Lines weren't respecting colors.
Added screen space markers as tiny elements in the layout engine.  Added layout importance support to the screen markers at the Component level.  Can now set the max number of objects for the layout engine to display.
Wasn't removing overlay views for the globe case.
Lofted poly cache bug.
Lighting problem fixed.  Should no longer turn up completely black.
