No difference between 100 and 300 font weight in Web Fonts

[GoogleCodeExporter]

Go to this page http://www.google.com/fonts/specimen/Lato
and you'll see that 100 and 300 fonts are similar. On Mac there is difference.

Comparison screen shot is attached.

windows only defined several weight "levels" as you can see from font selection 
dialog refered as "light regular bold" and some others I can't remember right 
now.
And only few fonts support all of them.

In windows, font weights in a predefined range will be treated as the same 
level. although freetype can render every weight separately as mac os does, 
mactype has to obey font weight level in order to simulate windows cleartype to 
output similar visual result.

I don't think it's Windows fault. I've been using these (Lato, OpenSans with 
various weights, from 100 to 500 etc) but when I installed MacType it all 
changed. Weird thing is that the problems is with Chrome and Firefox whereas IE 
display them correctly. Seee the screenshot of another font with wide range of 
weight (Roboto  - http://www.google.com/fonts#UsePlace:use/Collection:Roboto 
)below
