// Description:
// Invert the transformation. Warp transformations are usually
// inverted using an iterative technique such as Newton's method.
// The inverse transform is usually around five or six times as
// computationally expensive as the forward transform.

// Description:
// Get the inverse flag of the transformation. This flag is
// set to zero when the transformation is first created, and
// is flipped each time Inverse() is called.

// Set the tolerance for inverse transformation.

// Set the maximum number of iterations for the inverse
// transformation. The default is 500, but usually only
// 2 to 5 iterations are used. The inversion method
// is fairly robust, and it should converge for nearly all smooth
// transformations that do not fold back on themselves.
