> So it's actually working as intended. The 3MB limit doesn't seem particularly effective, though. Maybe we should increase that limit, but remove the special protection for root tiles?

The special protection for root tiles (potentially) makes tab switching faster because you don't have to repaint all of those tiles.  I know we already have slow tab switching issues, so I'd worry a little about making this worse.

I think somebody was looking at keeping around the fbo that we were drawing into.  If that got implemented, then I'd feel a lot more comfortable tossing all of the textures from a tab, because we'd have something to display while resources were recreated.
