 * These objects support visualization of flex containers by the
 * dev tools.

 * A flex container's main and cross axes are either horizontal or
 * vertical, each with two possible directions.
enum FlexPhysicalDirection {

interface Flex
  sequence<FlexLineValues> getLines();

   * The physical direction in which successive flex items are placed,
   * within a flex line in this flex container.
  readonly attribute FlexPhysicalDirection mainAxisDirection;

   * The physical direction in which successive flex lines are placed
   * in this flex container (if it is or were multi-line).
  readonly attribute FlexPhysicalDirection crossAxisDirection;

 * This indicates which flex factor (flex-grow vs. flex-shrink) the
 * flex layout algorithm uses internally when resolving flexible sizes
 * in a given flex line, per flexbox spec section 9.7 step 1. Note that
 * this value doesn't necessarily mean that any items on this line
 * are *actually* growing (or shrinking).  This simply indicates what
 * the layout algorithm "wants" to do, based on the free space -- 
 * and items will stretch from their flex base size in the corresponding
 * direction, if permitted by their min/max constraints and their
 * corresponding flex factor.
