Window stack unrolling

[fLindahl]

Hi,
I'm currently implementing a scripted imgui environment, using DearGui python bindings.
It's a fairly common mistake to omit the ::End() call, and thus get an assertion about it.

I was wondering if this will yield me any wierd behaviour or obscure bugs:

ImGuiContext* g = ImGui::GetCurrentContext();
while (g->CurrentWindowStack.Size > 1)
{
	printWarning("ImGui window missing ::End()!\n");
	ImGui::End();
}

This would spit tons of warnings, but at least not crash the application, which would be detrimental in my use case.
I've of course tried it out, and it seems to work fine, but I'm left wondering if it's a dirty hack or actually an OK way of doing it.
Are there any other ways of making ImGui less "strict" with assertions?

I'm aware that there are other places where missing a corresponding End call might assert as well, but I'll worry about those later.

Thanks!

This will work. Moving this thread to #1651 with a more complete answer.
