-    Calculate the "expanding" keyframe
-
-    This new keyframe sits between the already existing sizeAtPreferred and
-    sizeAtMaximum keyframes. Its goal is to modify the interpolation between
-    the latter as to respect the "expanding" size policy of some anchors.
-
-    Previously all items would be subject to a linear interpolation between
-    sizeAtPreferred and sizeAtMaximum values. This will change now, the
-    expanding anchors will change their size before the others. To calculate
-    this keyframe we use the following logic:
-
-    1) Ask each anchor for their desired expanding size (ad->expSize), this
-    value depends on the anchor expanding property in the following way:
-
-    - Expanding normal anchors want to grow towards their maximum size
-    - Non-expanding normal anchors want to remain at their preferred size.
-    - Sequential anchors wants to grow towards a size that is calculated by:
-        summarizing it's child anchors, where it will use preferred size for non-expanding anchors
-        and maximum size for expanding anchors.
-    - Parallel anchors want to grow towards the smallest maximum size of all the expanding anchors.
-
-    2) Clamp their desired values to the value they assume in the neighbour
-    keyframes (sizeAtPreferred and sizeAtExpanding)
-
-    3) Run simplex with a setup that ensures the following:
-
-      a. Anchors will change their value from their sizeAtPreferred towards
-         their sizeAtMaximum as much as required to ensure that ALL anchors
-         reach their respective "desired" expanding sizes.
-
-      b. No anchors will change their value beyond what is NEEDED to satisfy
-         the requirement above.
-
-    The final result is that, at the "expanding" keyframe expanding anchors
-    will grow and take with them all anchors that are parallel to them.
-    However, non-expanding anchors will remain at their preferred size unless
-    they are forced to grow by a parallel expanding anchor.
-
-    Note: For anchors where the sizeAtPreferred is bigger than sizeAtMaximum,
-          the visual effect when the layout grows from its preferred size is
-          the following: Expanding anchors will keep their size while non
-          expanding ones will shrink. Only after non-expanding anchors have
-          shrinked all the way, the expanding anchors will start to shrink too.
