Writes a centered string on a bitmap. allegro game programming library.
#include <allegro.h>
void textout_centre_ex(BITMAP *bmp, const FONT *f, const char *s, int x, y, int color, int bg);
Like textout_ex(), but interprets the x coordinate as the centre rather than the left edge of the string. Example:
/* Important texts go in the middle. */
width = text_length("GAME OVER");
textout_centre_ex(screen, font, "GAME OVER",
SCREEN_W / 2, SCREEN_H / 2,
makecol(255, 0, 0), makecol(0, 0, 0));
