What is "PlacementOffset" on gobo wheels

Lots of gobo wheels have this but I can't find a description of what it is.

Hello @Ben-Garcia-Data , the PlacementOffset allows us to indicate the location of the wheel in relation to the beam, thus, visualizers can know if the wheel rotation happens horizontally or vertically (or diagonally, if ever). At this point i am not aware of anyone utilizing it. See the original issue #10, PR mvrdevelopment/gdtf-din-spec#6 , then the final PR mvrdevelopment/gdtf-din-spec#4
