draw_character_ex - Draws non transparent pixels of the sprite with a color. Allegro game programming

       Draws a copy of the sprite bitmap  onto  the  destination  bitmap  at  the  specified  position,  drawing
       transparent  pixels  in the background color (or skipping them if the background color is -1) and setting
       all other pixels to the specified color. Transparent pixels are marked by a zero in  256-color  modes  or
       bright  pink  for  truecolor  data (maximum red and blue, zero green). The sprite must be an 8-bit image,
       even if the destination is a truecolor bitmap. Example:

          BITMAP *logo;
          ...
          /* Draw the logo silhouette in red. */
          draw_character_ex(screen, logo, SCREEN_W / 2, SCREEN_H / 2,
                            makecol(255, 0, 0), -1);
