Couple issues. A rotated object does not seem to be aligning right. We apparently fixe this in 016 but just witnessed a non centered rotated object.
I think it would be best to make a container for each tile element that is the dimensions and positions based on either colSize, rowSize or max values of cols and rows. If squeeze then this becomes the tile size but then aligned. Then once the objects are positioned, add them to the Tile directly and dispose the positioning container. I think we did that for Pack.
STYLE series for align is coming through... but for some reason, the positioning is not paying attention - again the rewrite to pos() for each tile should make this easy.
