Render an SIO2ipocurve, calculating the interpolation of the curve based on the selected method. This method can be either one of the following values:
SIO2_IPO_CURVE_INTERPOLATION_CONSTANT
SIO2_IPO_CURVE_INTERPOLATION_LINEAR
SIO2_IPO_CURVE_INTERPOLATION_BEZIER

SIO2_IPO_CURVE_EXTRAPOLATION_CONSTANT
SIO2_IPO_CURVE_EXTRAPOLATION_EXTRAPOLATION
SIO2_IPO_CURVE_EXTRAPOLATION_CYCLIC
SIO2_IPO_CURVE_EXTRAPOLATION_CYCLIC_EXTRAPOLATION
_SIO2ipocurve: A valid SIO2ipocurve structure pointer.
_SIO2window: A valid SIO2window structure pointer used to increment the delta time of the SIO2ipocurve.
return the value of the current SIO2ipocurve.
