This class represents the VUE File Renderer. It lets you construct an instance of the VUE_File_Renderer class to be assigned
to the Current and Production renderers using the new renderers structure.
No properties or interfaces exposed.
EXAMPLE
--Create a new instance of the VUE_File_Renderer class
vue_rend = VUE_File_Renderer ()
--> VUE_File_Renderer:VUE_File_Renderer
--Assign the VUE renderer to the current renderer
--Since assigning a new renderer generates
--an invalid undo record,
--we turn undo off temporarily
undo off renderers.current = vue_rend
--> VUE_File_Renderer:VUE_File_Renderer
