rotate_sprite - Rotates a sprite. Allegro game programming library.

       Draws  the sprite image onto the bitmap. It is placed with its top left corner at the specified position,
       then rotated by the specified angle around its centre. The angle is a fixed point  16.16  number  in  the
       same  format  used  by  the fixed point trig routines, with 256 equal to a full circle, 64 a right angle,
       etc. All rotation functions can draw between any two bitmaps, even screen bitmaps or bitmaps of different
       color depth.

       Positive increments of the angle will make the sprite rotate clockwise on the screen, as demonstrated  by
       the Allegro example.
