the class Envelopes method transform.

 * or when it cross the ±180° longitude.</p>
 *
 * <div class="note"><b>Note:</b>
 * If the envelope CRS is non-null, then the caller should ensure that the operation source CRS
 * is the same than the envelope CRS. In case of mismatch, this method transforms the envelope
 * to the operation source CRS before to apply the operation. This extra step may cause a lost
 * of accuracy. In order to prevent this method from performing such pre-transformation (if not desired),
 * callers can ensure that the envelope CRS is {@code null} before to call this method.</div>
 *
 * @param  operation  the operation to use.

         * Checks for singularity points. For example the south pole is a singularity point in
         * geographic CRS because is is located at the maximal value allowed by one particular
         * axis, namely latitude. This point is not a singularity in the stereographic projection,
         * because axes extends toward infinity in all directions (mathematically) and because the
         * South pole has nothing special apart being the origin (0,0).
         *
         * Algorithm:
         *
         * 1) Inspect the target axis, looking if there is any bounds. If bounds are found, get
         *    the coordinates of singularity points and project them from target to source CRS.
         *
         *    Example: If the transformed envelope above is (80 … 85°S, 10 … 50°W), and if the
         *             latitude in the target CRS is bounded at 90°S, then project (90°S, 30°W)
         *             to the source CRS. Note that the longitude is set to the the center of
         *             the envelope longitude range (more on this below).
         *
         * 2) If the singularity point computed above is inside the source envelope, add that
         *    point to the target (transformed) envelope.
         *
         * 3) If step #2 added the point, iterate over all other axes. If an other bounded axis
         *    is found and that axis is of kind "WRAPAROUND", test for inclusion the same point
         *    than the point tested at step #1, except for the ordinate of the axis found in this
         *    step. That ordinate is set to the minimal and maximal values of that axis.
         *
         *    Example: If the above steps found that the point (90°S, 30°W) need to be included,
         *             then this step #3 will also test the points (90°S, 180°W) and (90°S, 180°E).
         *
         * NOTE: we test (-180°, centerY), (180°, centerY), (centerX, -90°) and (centerX, 90°)
         * at step #1 before to test (-180°, -90°), (180°, -90°), (-180°, 90°) and (180°, 90°)
         * at step #3 because the later may not be supported by every projections. For example
         * if the target envelope is located between 20°N and 40°N, then a Mercator projection
         * may fail to transform the (-180°, 90°) coordinate while the (-180°, 30°) coordinate
         * is a valid point.
