Font Anti-Aliasing Issues in HTML/Ajax based Air Applications

It seems that the font-renderer in HTML/Ajax based Air Applications is using some kind of sub-pixel font renderer that is overriding and vastly inferior to the standard Windows ClearType, or any Apple based option as well.  This problem is particularly noticable with light text on a dark background, and made worse the smaller the text is.  I've put together an example image explaining exactly what I mean at: http://regator.com/fontRendering.png   (it's a large image 1126 x 1500 px)

My example shows two fonts at four different sizes rendered in an HTML Air App vs the default Windows Cleartype, as well as using Safari to show the Font style anti-aliasing.  In all cases the HTML Air App rendering is far more difficult to read, and in many cases severely distorts the color of the text in a way that other subpixel algorithms do not.  As far as I can find after literally hours of googling and searching there's no way to override this in HTML based applications.  Is there any solution to this, or a planned fix for the renderer?  Other than this rendering issue, the HTML interface for creating Air apps is absolutely brilliant, this is just making my finished product look significantly less polished than it otherwise would if the text were more readable.

Thanks.
