Reviewed by David Hyatt.

Source/WebCore:

The shape-outside property can now be set to the box values [margin/border/padding/content]-box.
This patch adds the parsing code required to accept the new values, and the layout code
to create a rectangle shape that has the size and position of the appropriate box.
