rotate_sprite_v_flip_trans - Rotates and flips a sprite. Allegro game
programming library.
#include <allegro.h>
void rotate_sprite_v_flip_trans(BITMAP *bmp, BITMAP *sprite,
int x, int y, fixed angle);
Like rotate_sprite_trans, 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.
