tvfontsize_c DEPRECATED

	tvfontsize_c(fsize.i4.v)

	Sets the font sized used in the color TV window.  Normally, the
	program should not set the font size, but if a program uses a very 
	large window size, it may want to set the font size to ensure that
	the window will fit on the screen.

	fsize		desired font size
			  TVFONT_SMALL		size 1 TV font
			  TVFONT_MEDIUM		size 2 TV font
			  TVFONT_LARGE		size 3 TV font
			  TVFONT_NOTLARGE	IF size 3 THEN size 2 TV font
