status.i4.v = wn_text_attributes_c(bkgd_mode.i4.v, video_mode.i4.v)

	This routine sets the current text drawing modes for graphical windows.

	bkgd_mode	character background drawing mode
			(WN_TEXT_ERASIVE -> text background is erased,
			 WN_TEXT_ADDITIVE -> text background is not erased)
	video_mode	foreground/background color mode
			(WN_TEXT_NORMAL -> normal text,
			 WN_TEXT_INVERSE -> inverse video text)

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid text mode(s)
