Hi,

Before all, I have to apologize that I vote No in spite of
I'm not GTK+/Win95 developer.

I remember, a guy was trying to port cairo to Win9x, although
yet I've not heard successful report, at present.

Dropping Win9x code from HEAD means "GTK+ 2.12 won't support for
Win9x"? Excuse me, I don't understand what you mean "enough".

I see. Do you think it is possible that packaging Win95 support
code as separate library?

Ah, sorry, I was confused and my English is too poor.
Let me explain wordily.

I guess, the import Uniscribe into pangowin32 is requested to
add complex script rendering feature to pangowin32 itself.
By Uniscribe rendering, the complex script rendering would
be exactly same with popular Win32 applications (e.g. wordpad.exe).
I guess it is the advantage prioritized by the people who
request default-and-builtin Uniscribe support. Am I right?
