NAME
       stretch_sprite - Stretches a sprite to the destination bitmap. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void stretch_sprite(BITMAP *bmp, BITMAP *sprite, int x, int y, int w, int h);

DESCRIPTION
       Like  draw_sprite(), except it can stretch the sprite image to the specified width and height and requires the sprite image and destination
       bitmap to be of the same color depth. Moreover, the sprite image must be a memory bitmap. Example:

          /* Create tunnel like effect. */
          for (step = 1; step
             int width = SCREEN_W / step;
             int height = SCREEN_H / step;
             stretch_sprite(screen, image, SCREEN_W / 2 - width / 2,
                            SCREEN_H / 2 - height / 2, width, height);
          }
