OK. Doesn't sound too promising, then.

Yes. For GTK+ 2.10 the situation is the same as for 2.8, i.e. it would
presumably work otherwise, if cairo would.

Yes. The "separate library" is calld GTK+ 2.6 ;)

Yes. ("would" is wrong, it *is* (one would hope) and has been for a
long time.)

Hmm, I don't really understand what you mean here. There are no
alternatives to Uniscribe for Pango on Win32. There is code in Pango
itself for complex script processing only when using the
fontconfig-based backends.

The Uniscribe use in Pango is currently optional both during
configuration/compilation, and during runtime. I am suggesting that
the optionality during configuration/compilation could be
removed. (Thus one would have to have the Platform SDK, or at least
just usp10.h, on the machine where one builds Pango.)

The code would still check at run-time for the availability of
usp10.dll, and link to it dynamically. Thus one might still be able to
use pangowin32 on Win9x... but that is mostly a pointless fact as GTK+
uses pangocairo (which uses cairo and pangowin32).
