gtk+-2.18, win32, and OpenGL

[Tim Evans <t evans aranz com>]

Previous with GTK+ 2.14 I had some custom code that would let me draw 
with OpenGL into a widget under win32.  After updating GTK+ 2.18 this 
code doesn't work properly any more, it turns the entire toplevel window 
into an OpenGL area instead.

I've gotten part way to having it work by calling 
gdk_window_ensure_native() on the window behind my OpenGL area widget, 
but some things are still broken:

1. I've found I need to call SetWindowPos manually to resize the native 
window when the widget is allocated.  Is this the expected behaviour?

2. Mouse events seem to be screwed up.  After clicking on my OpenGL area 
widget, other widgets will not receive enter-notify-event until I click 
again outside the widget, making buttons and other widgets not work.  Is 
there a way to fix this?

3. Are either of gtkglext or gtkglarea known to work correctly with GTK+ 
2.18 on win32?

Thanks in advance.
