Invisible GtkImage

[Kip Warner <kip thevertigo com>]

Hey list,

I am attempting to create a GtkImage that resizes to fill its parent
container while maintaining its aspect ratio. I do this by subclassing
GtkImage and overriding do_size_allocate().

        <http://pastebin.com/SD4RBkes>

The code mostly works in that I can see that the area the widget is
taking appears to be the correct size as I resize its parent. However,
the actual image pixels do not appear to be painted.

Any help appreciated,
