2.16 vs 2.18 difference

[Patrick Welche <prlw1 cam ac uk>]

I am trying to track down https://bugzilla.gnome.org/show_bug.cgi?id=607775
and it is beginning to look like a regression in gtk 2.16 -> 2.18, but it
I am finding it hard to put my finger on what changed.

Basically, if you start dasher on a gtk 2.18 + cairo system, the
GtkDrawingArea is the default grey. On a gtk 2.16 + cairo system, it is
drawn correctly. Using gtk + gdk, it is also drawn correctly.

The last point suggests that dasher's event handling is correct...
There are many inter-library dependences, so it's hard to know which one
is the root cause.

Do any of you recognise this?

Cheers,

Patrick
