library.
#include <allegro.h>
void rotate_sprite_v_flip(BITMAP *bmp, BITMAP *sprite, int x,
int y, fixed angle);
Like rotate_sprite, but flips the image vertically before rotating it. To flip
horizontally, use this routine but add itofix(128) to the angle. To flip in
both directions, use rotate_sprite() and add itofix(128) to its angle.
