Changed hidden surface removal test to use screen coords area sign test - no longer see popping polygons as they disapear from view. Removed hiddenangle style settings as no longer required.
Debug entity to show axis, and show position and entity id at runtime. See Phoria.Entity.debug()
Added 'front' and 'back' to object sortmode style to allow rendering over other objects for debug labels etc.
Fix to ensure newly added scene trigger functions are not executed until next scene processing loop.
Minor bug fix to potential issue with null local matrix on solid objects.
