The latest release introduced a new function IVRDisplayComponent::ComputeInverseDistortion in the driver interface (

openvr/headers/openvr_driver.h

Lines 2900 to 2902 in f51d87e

    
           		/** Computes the result of the inverse distortion function for the specified eye, channel, and input UV. 
        
           		* Operation can fail, returns success/failure, on success result is stored in *pResult */ 
        
           		virtual bool ComputeInverseDistortion( HmdVector2_t *pResult, EVREye eEye, uint32_t unChannel, float fU, float fV ) = 0;

).

My understanding is that this function is called by the runtime opportunistically to improve the inverse warping transformation.

It seems that on my driver this function is not called. Are there some other conditions which must be met in order to have the runtime call it?
What exactly is this function supposed to improve, or when is it advised to implement it?
