Do you think this wording is any better?

    void draw_sprite(BITMAP *bmp, BITMAP *sprite, int x, int y);
       Draws a copy of the sprite bitmap onto the destination bitmap at 
       the specified position. This is almost the same as blit(sprite, 
       bmp, 0, 0, x, y, sprite->w, sprite->h), but it uses a masked 
       drawing mode where transparent pixels are skipped, so the 
       background image will show through the masked parts of the 
       sprite. Transparent pixels are marked by a zero in 256 color 
       modes or bright pink for truecolor data (maximum red and blue, 
       zero green).
