  tjLoadImage(): Don't convert RGB to grayscale
  
  Loading RGB image files into a grayscale buffer isn't a particularly
  useful feature, given that libjpeg-turbo can perform this conversion
  much more optimally (with SIMD acceleration on some platforms) during
  the compression process.  Also, the RGB2GRAY() macro was not producing
  deterministic cross-platform results because of variations in the
  round-off behavior of various floating point implementations, so
  `tjunittest -bmp` was failing in i386 builds.
