Great to see progress on this one, however not fully fixed yet. Calibri and Cambria size < 15 (at zoom=100%) are not antialiased. You can see this also on the latest screenshot by rui1965@voila.fr in the format-section of the toolbar.
Many fonts with truetype bytecode hinting directly forbid antialiased rendering at some ppem sizes (via its 'gasp' table) to prevent bad or unexpected rendering results.
