Developing a widget - help with introspection and feedback

[Rena <hyperhacker gmail com>]

Hi all, I'm developing my first GTK widget. I have it working OK, but I
can't get g-ir-scanner to cooperate.

Right now it's just a simple test widget (displays some text); later it
will display charts and graphs.
gtk-display.h: http://pastebin.com/7j6B4371
gtk-display.c: http://pastebin.com/G41uDQeE
test.c: http://pastebin.com/CMXduE5T
makefile: http://pastebin.com/b4xFv1jb

I'm not sure if I'm following all the conventions correctly, so feedback on
that would be nice. Also I get an error with g-ir-scanner:

Again I might just be doing that wrong, or I'm encountering
https://bugzilla.gnome.org/show_bug.cgi?id=699442 ? I'm not really sure.
