gammacorrect
This function is used to compensate for the nonlinearity of CRT display systems.
If t varies over the [0,1] interval, then the result is also in that interval.
The zero and one endpoints are mapped onto themselves.
Other values are shifted upward toward one if gamma is greater than one,
and shifted downward toward zero if gamma is between zero and one.
gammacorrect(gamma,t) Returns a value t shifted upwards or downwards depending on the given gamma value.

** Usage:
** out = gammacorrect(gamma,t);

** Arguments:

** Returns:

** the result also varies over that interval.
** The zero and one endpoints of the interval
** are mapped onto themselves. Other values
** are shifted upward toward one if (gamma) is
** greater than one, and shifted downward
** toward zero if (gamma) is between zero and one.
