				draw_venn.c

Purpose:
	Draw Venn diagram.  This function is used if the main win. drawing
	mode is equal to three. The sequence stored to the sequence buffer
	is used to prepare the Venn diagram.

Input:
	(1) Pointer to RuntimeS structure, with some runtime data.
	(2) Pointer to GUIS structure, with GUI data.
	(3) Pointer to NearestAtomS structure,  with information about the
	    atom occupying the given pixel.
	(4) The number of pixels in the main window free area.
	(5) The refreshI,  used to check the  NearestAtomS associated with
	    a given pixel. It is currently unused in this function.

Output:
	(1) Venn diagram drawn to the main window.
	(2) Return value.

Return value:
	(1) The number of residues used to prepare the Venn diagram.

Notes:
	(1) The initial drawing destination is the hidden pixmap,  and the
	    content of this pixmap is copied later to the main window.

	(2) Cysteine is treated  in a special way:  cysteine which  is not
	    involved in a disulfide bond should be treated as polar, while
	    cysteine which takes part  in disulfide bond  formation is not
	    polar.
