What does what do? The interpolation funcion?
Linear interpolation returns a value which is (proportionally) at the same
distance between TS and TE as GC is between GS and GE.
EXP > 1 makes the value "accelerate" as it goes from TS to TE, i.e. it changes a
little towards the start and a lot towards the end.
EXP < 1 makes the value "decelerate"

Sorry, lost count of the words ;)
