That's an opinion you can have.  Personally once an API has been 
deprecated for seven years I don't feel too bad about needing to fix the 
consumers.  But feel free to bring that concern to pango.  Me, I prefer 
fixing things.

The affected API appears to be almost unused.  gauche-gtk, ruby-gnome2, 
pygtkglext and gtkglextmm do wrap and export the API, but none of their 
consumers use it, at least not in Fedora.

The actual consumers appear to be:

gabedit/GabeditSrc240/src/Utils/UtilsGL.c
k3d/k3d-source-0.8.0.2/k3dsdk/ngui/viewport.cpp
ghemical/ghemical-2.99.2/src/pangofont_wcl.cpp

The affected API is basically a complicated wrapper around glXUseXFont, 
itself a mildly unfortunate convenience API (display list full of 
glBitmap calls? thanks for the software fallback hit), and one that 
requires an actual X font.  One could probably hack around that by 
making a bitmap with XftDrawCreateBitmap, using pangoxft to render into 
it, and then reimplementing the rest of UseXFont from that bitmap. 
Actually pretty straightforward.  Still going to be brutally slow on the 
open 3D drivers, but it'd work.

That said it's probably less work to grab a copy of pango-1.30.1 and 
just build compat-pangox from that.
