Subpixel rendering vm build?

Is there a specific reason to not have a pharo vm build with
subpixel rendering for non-US use?

Why do you think there are different builds?

Shouldn't there be?
EU has higher standards for software patents, so
there are no ClearType patents in EU afaik.

Why you think there's something in VM that blocking it?

Or, if you speaking about Athens, i tried multiple times to 'fix' the problem and force Cairo to render fonts with subpixel quality.. no luck :(

And Freetype package has own subpixel renderer implementation (in smalltalk , just FYI look at the code of applying a gamma-filter

So, if you think you can do better, and feel adventurous, you can start from
FreeTypeGlyphRenderer

and improve it..

I had impulses, once before to clean it up and

1-st, understand what is going on

2-nd see how this can be improved.

But you can look at this code, and let me know if it violates patent(s) or not  :)
