20160605 14:35:58< vultraz> Aginor: so I've been doing some work for Argentum Age, and I noticed they have a pretty nice zorder draw system. Basically, different objects specify a zorder and they're drawn in that order. I was thinking maybe wesnoth could do something similar, instead of that window manager idea we had been throwing around. Add a zorder property to the draw stack, and when a redraw happens, maybe redraw...

20160605 14:38:42< vultraz> Aginor: the tdrawing_layer enum basically has all the layers rendering functions take as arguments. If that could be expanded to GUI2 we could have effects between windows by simply saying "draw x effect at zorder-10" or something
20160605 14:39:14< vultraz> Aginor: it does still raise the question of multiple stacked windows, since we may not want effects to double up, so that could still be an issue
