Specifies the desired layout direction for an element: one of LayoutDirection.LTR
(left to right), LayoutDirection.RTL (right to left), or null (inherit).
This property is typically backed by an inheriting style. If null,
the layoutDirection style will be set to undefined.
Classes like GraphicElement, which implement ILayoutDirectionElement but do not
support styles, must additionally support a null value for this property
which means the layoutDirection must be inherited from its parent.

An element must call this method when its layoutDirection changes or
when its parent's layoutDirection changes.
If they differ, this method is responsible for mirroring the element’s contents
and for updating the element’s post-layout transform so that descendants inherit
a mirrored coordinate system. IVisualElements typically implement
mirroring by using postLayoutTransformOffsets to scale the X axis by -1 and
to translate the x coordinate of the origin by the element's width.
The net effect of this "mirror" transform is to reverse the direction
in which the X axis increases without changing the element's location
relative to its parent's origin.
