NAME
       GetRPAttrA -- examine rastport settings via a tag list
	GetRPAttrs  -- varargs stub for GetRPAttrA

   SYNOPSIS
       GetRPAttrA(rp,tags)
                  a0   a1

	void GetRPAttrA(struct  RastPort *, struct  TagItem *);

	GetRPAttrs(rp,attr1,&result1,...);

   FUNCTION
       Read the settings of a rastport into variables. The
	ti_Tag field of the  TagItem specifies which attribute
	should be read, and the ti_Data field points at the
	location where the result hsould be stored. All current
	tags store the return data as LONGs (32 bits).

	currently available tags are:

		RPTAG_Font		Font for  Text()
		RPTAG_SoftStyle		style for text (see  sc:include/graphics/text.h)
		RPTAG_APen		Primary rendering pen
		RPTAG_BPen		Secondary rendering pen
		RPTAG_DrMd 		Drawing mode (see  sc:include/graphics/rastport.h)
		RPTAG_OutLinePen 	Area Outline pen
		RPTAG_WriteMask 	Bit Mask for writing.
		RPTAG_MaxPen 		Maximum pen to render (see  SetMaxPen())
		RPTAG_DrawBounds	Determine the area that will be rendered
					into by rendering commands. Can be used
					to optimize window refresh. Pass a pointer
					to a rectangle in the tag data. On return,
					the rectangle's MinX will be greater than
					its MaxX if there are no active cliprects.

   INPUTS
	rp - pointer to the  RastPort to examine.
	tags - a standard tag list specifying the attributes to be read,
		and where to store their values.
