0027  * Since 12-bit data precision is an opt-in feature that requires explicitly
0028  * calling 12-bit-specific libjpeg API functions and using 12-bit-specific data
0029  * types, the unmodified portion of the libjpeg API still behaves as if it were
0030  * built for 8-bit precision, and JSAMPLE is still literally an 8-bit data
0031  * type.  Thus, it is correct to define BITS_IN_JSAMPLE to 8 here.
