SYNOPSIS
       #include <allegro.h>

       void do_circle(BITMAP *bmp, int x, int y, int radius, int d, void (*proc)(BITMAP *bmp, int x, int y, int d));

DESCRIPTION
       Calculates  all the points in a circle around point (x, y) with radius r, 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:

	  {
	     ...
	  }

	     do_circle(screen, SCREEN_W/2, SCREEN_H/2,
