Subject: [PATCH] tools(LayoutDump): print the BUILT widget tree beside the
 authored one

"This control is in the wrong place" has exactly two possible causes: the dat
authored it there, or our importer moved it. Printing only the authored tree
answers half the question.

--built runs LayoutImporter.Build over the same ElementInfo and prints the
resulting widget geometry underneath, so the two can be compared directly. On
the effects window they match exactly, which is how the "misaligned scrollbar"
report was ruled out as an import bug rather than assumed to be one.
