+ * After measurement, the derived class must also call SetMeasuredDimensions to set it's own requested size.

+ * OnLayout should use it's own layout parameters and the measured children's size to determine the children's

+// This is the main routine that implements a subset of the flexbox layout
+// algorithm
+// described in the W3C YG documentation: https://www.w3.org/TR/YG3-flexbox/.
+//
+// Limitations of this algorithm, compared to the full standard:
+//  * Display property is always assumed to be 'flex' except for Text nodes,
+//  which
+//    are assumed to be 'inline-flex'.
+//  * The 'zIndex' property (or any form of z ordering) is not supported. Nodes
+//  are
+//    stacked in document order.
+//  * The 'order' property is not supported. The order of flex items is always
+//  defined
+//    by document order.
+//  * The 'visibility' property is always assumed to be 'visible'. Values of
+//  'collapse'
+//    and 'hidden' are not supported.
+//  * There is no support for forced breaks.
+//  * It does not support vertical inline directions (top-to-bottom or
+//  bottom-to-top text).
+//
+// Deviations from standard:
+//  * Section 4.5 of the spec indicates that all flex items have a default
+//  minimum
+//    main size. For text blocks, for example, this is the width of the widest
+//    word.
+//    Calculating the minimum width is expensive, so we forego it and assume a
+//    default
+//    minimum main size of 0.
+//  * Min/Max sizes in the main axis are not honored when resolving flexible
+//  lengths.
+//  * The spec indicates that the default value for 'flexDirection' is 'row',
+//  but
+//    the algorithm below assumes a default of 'column'.
+//
+// Input parameters:
+//    - node: current node to be sized and layed out
+//    - availableWidth & availableHeight: available size to be used for sizing
+//    the node
+//      or YGUndefined if the size is not available; interpretation depends on
+//      layout
+//      flags
+//    - ownerDirection: the inline (text) direction within the owner
+//    (left-to-right or
+//      right-to-left)
+//    - widthMeasureMode: indicates the sizing rules for the width (see below
+//    for explanation)
+//    - heightMeasureMode: indicates the sizing rules for the height (see below
+//    for explanation)
+//    - performLayout: specifies whether the caller is interested in just the
+//    dimensions
+//      of the node or it requires the entire node and its subtree to be layed
+//      out
+//      (with final positions)
+//
+// Details:
+//    This routine is called recursively to lay out subtrees of flexbox
+//    elements. It uses the
+//    information in node.style, which is treated as a read-only input. It is
+//    responsible for
+//    setting the layout.direction and layout.measuredDimensions fields for the
+//    input node as well
+//    as the layout.position and layout.lineIndex fields for its child nodes.
+//    The
+//    layout.measuredDimensions field includes any border or padding for the
+//    node but does
+//    not include margins.
+//
+//    The spec describes four different layout modes: "fill available", "max
+//    content", "min
+//    content",
+//    and "fit content". Of these, we don't use "min content" because we don't
+//    support default
+//    minimum main sizes (see above for details). Each of our measure modes maps
+//    to a layout mode
+//    from the spec (https://www.w3.org/TR/YG3-sizing/#terms):
+//      - YGMeasureModeUndefined: max content
+//      - YGMeasureModeExactly: fill available
+//      - YGMeasureModeAtMost: fit content
+//
+//    When calling YGNodelayoutImpl and YGLayoutNodeInternal, if the caller passes
+//    an available size of
+//    undefined then it must also pass a measure mode of YGMeasureModeUndefined
+//    in that dimension.
