NAME
       do_ellipse - Calculates all the points in an ellipse. Allegro game pro-
       gramming	library.

SYNOPSIS
       #include	<allegro.h>

       void  do_ellipse(BITMAP	*bmp,  int  x,	int y, int rx, ry, int d, void
       (*proc)(BITMAP *bmp, int	x, int y, int d));

DESCRIPTION
       Calculates all the points in an ellipse around point (x,	y) with	radius
       rx and ry, calling the supplied function	for each  one.	This  will  be
       passed a	copy of	the bmp	parameter, the x and y position, and a copy of
       the d parameter,	so it is suitable for use with putpixel(). Example:

	  void draw_explosion_ring(BITMAP *bmp,	int x, int y, int d)
	  {
	     ...
	  }

	     do_ellipse(screen,	SCREEN_W/2, SCREEN_H/2,
		       SCREEN_H/16, SCREEN_H/32, flame_color,
		       draw_explosion_ring);
