GtkGlExt woes

[Jeff 'japhy' Pinyan <japhy perlmonk org>]

I'm having the following problem.  I have a Notebook widget, and I want to 
display DrawingArea widgets on multiple tabs of the Notebook.  The
DrawingArea widgets are GL-enabled.  When I switch tabs, none of my 
textures appear on the DrawingArea I've just switched to.  If I go back to 
the FIRST tab displayed, THAT DrawingArea works fine.

I'd use the "share_list" feature if I could, but I can't, because that 
seems to require the GL-enabled widget to already be realized, but all 
these widgets are being made at the same time and I can't seem to get them 
to realize soon enough.

I've also tried just having ONE DrawingArea, and changing its parent each 
time the tab is changed, but that resulted in no textures showing up after 
I changed tabs.  It appears the widget gets a new gl_context and even 
sometimes a new gl_drawable.

If this can't be resolved, I'm probably going to try having a pop-up 
window that displays the OpenGL rendering, but that's really irritating.
