+Internal color values
+---------------------
+
+Previously, Mesa treated color channel values as GLubytes in [0,255].
+Mesa 3.5 uses the GLchan datatype for color channel values.  In the
+future it will be possible to define GLchan to be larger than a byte
+in order to support high-precision colors.
+
+Many, many occurances of GLubyte have been replaced with GLchan
+and many occurances of the number 255 have been replaced with CHAN_MAX.
+
+Support for CHAN_BITS > 8 is not ready yet but will be eventually.
