-		Two mistakes in the algorithm currently:
-

-			<li>Step 2 needs to take into account the major-axis spans of every item as well.  Otherwise, extra-wide single items can create new columns late in auto-placement.
-
-			<li>Step 4 needs to verify that placement also doesn't cause the item to generate new columns.  Currently, it only verifies that placement won't overlap anything else.

 		Edit the algorithm to allow for dense packing.
