SYNOPSIS

       #include <allegro.h>

       void arc(BITMAP *bmp, int x, y, fixed ang1, ang2, int r, int color);

DESCRIPTION

       Draws a circular arc with centre x, y and radius r, in an anticlockwise direction starting
       from the angle a1 and ending when it reaches a2. These values are specified in 16.16 fixed
       point format, with 256 equal to a full circle, 64 a right angle, etc. Zero is to the right
       of the centre point, and larger values rotate anticlockwise from there. Example:

          /* Draw a black arc from 4 to 1 o'clock. */
          arc(screen, SCREEN_W/2, SCREEN_H/2,
              itofix(-21), itofix(43), 50, makecol(0, 0, 0));
