Positioned elements

Now that image and table resizing in Composer and mail composition is done and about to land in the trunk for 1.3 final, I am working on support for absolutely positioned elements in Composer. It will be possible to extract any replaced element or block-level element from the normal flow of the document, drag-and-drop it to any location in the canvas, and even un-pin it to put it back in its original location in the normal flow. Stay tuned.
