[Wine] Font anti-aliasing in wine?

[hasi]

One of the things that DOES make a big difference for me is font-antialiasing (AA). (OK, maybe I am picky). Does anyone have experience/knowledge on that subject? 
What surprises me is that for a few fonts (BitStream Vera Sans, for instance), it is active, whereas it is completely absent for most others. Why is that? (BTW, I just found out that I get the best results so far for the new MS font "Corbel"--I admit not a very "free" solution, but a practical one. I now have set this as the default font for menus, tooltips, etc.)

For instance, in the Word documents I am editing, AA kicks in above a certain font size (or document magnification/zoom), but seems to be switched off below. Is that a parameter that can be set somewhere? Also, in a Word document, if I select a magnification which renders a certain font with AA, the same characters would not be AA'ed for italic letters. ???

The AA I have seen happen in wine is a simple AA only ("grayscale"). Ultimately, of course, one would like to see subpixel-AA (like ClearType in Windows) in wine applications, which is now widely available on linux through freetype2. Can that be switched on in wine? 
Any thoughts/ideas/knowledge about AA under wine would be interesting. Thanks very much.
