So this is what Qt does:
http://www.qt.gitorious.org/qt/qt/blobs/4.7/src/gui/text/qfontengine_x11.cpp#line1038

I think the difference is that Pango has its own class to represent a set of
fonts, so it will only pass one font at a time to fontconfig (which allows
getting the settings for the exact font containing the glyph), whereas Qt
actually uses freetype's glyph lookup, which unfortunately means fontconfig
gets only the whole list of fonts to work with.

The Pango approach looks pretty much like a hack around the limitations in
fontconfig and freetype to me.

So I still think that it is impractical to change Qt and that the lohit fonts
must be fixed to zap the unwanted hinting bytecode from the fonts themselves as
was done for lohit-devanagari-fonts and drop the fontconfig settings.
