)

 Draws UV displacement map within the output render target.
Public function Const float

GetUndistortOverscanFactor ( float DistortedHorizontalFOV,
float DistortedAspectRatio
)

 Returns the overscan factor required for the undistort rendering to avoid unrendered distorted pixels.
Public function Const FVector2D Undistorts 3d vector (x, y, z=1.f) in the view space and returns (x', y', z'=1.f).
