Freetype relies on gazillion of empirical constants in the code. Not a
single one of those was has ever been promoted to a configuration
file. All of the sudden these 4 pair have an incredible honor to be
configurable. Why? What is so special about them? I am willing to bet
that nobody has touched them or will ever touch them. Apparently,
nobody can even explain what they mean. Put them back in the code,
please! Frankly, I am puzzled.
