v0.9.10
Changed hidden surface removal test to use screen coords area sign test - no longer see popping polygons as they disappear from view. Removed 'hiddenangle' style settings as no longer required.
Debug method added - to show entity XYZ axis, also 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.
