Well....., I have discovered this GRAYS_USE_GAMMA as well and I am
preparing a message to start discussing how to get this enabled in the
standard release.  Than a 2 segment linear aproximation to the
gamma = 2.4 curve is not good enough, and I will propose a a better
solution.

Please join that discussion.
