[12] Fixed a bug in the build system that was causing the Windows version of
wrjpgcom to be built using the rdjpgcom code.
+[13] Restored 12-bit-per-component JPEG support. A 12-bit version of
+libjpeg-turbo can now be built by passing an argument of --with-12bit to
+configure (Unix) or -DWITH_12BIT=1 to cmake (Windows.) 12-bit JPEG support is
+included only for convenience. Enabling this feature disables all of the
+performance features in libjpeg-turbo, as well as arithmetic coding and the
+TurboJPEG API. The resulting library behaves no differently than libjpeg v6b.
