itofix - Converts an integer to fixed point. Allegro game programming library.

       Converts  an integer to fixed point. This is the same thing as x<<16.  Remember that overflows (trying to
       convert an integer greater than 32767) and underflows (trying to convert an integer lesser  than  -32768)
       are not detected even in debug builds! The values simply "wrap around". Example:

          fixed number;
          /* This conversion is OK. */
          number = itofix(100);
          ASSERT(fixtoi(number) == 100);
          number = itofix(64000);
          /* This check will fail in debug builds. */
          ASSERT(fixtoi(number) == 64000);
