GtkGLExt does not seem to work with newer versions of Pango.
I keep getting the error: "GdkGLExt-WARNING **: cannot load PangoFont"
I tried the Windows binaries at: http://www.bonifazi.eu/appunti/2008/02/gtk-glade-gtkglext-all-in-one-windows.html
I downloaded the installer that includes Gtk+, Glade and GtkGlext.
When I try to open font.exe from the examples, I get this error:
(font.exe:1264) GdkGLExt-WARNING **: cannot load PangoFont
***Can't load font 'courier 12'
This installer includes Pango version 1.24.0.
If I switch to version 1.24.2-1 (the newest one available right now) the problem persists.
