1109   Vname is the coefficient defined in funcfile that determines the influence
1110   of foreground.
1111   The background coefficient is always (1-vname).
1112 Since the references are not resolved until runtime, the last
1113 definitions of the modifier id's will be used.
1114 This can result in modifier loops, which are detected by the
1115 renderer.
