Editor crashes upon start about acid HOT 3 OPEN

Bug of window signal connection is because there is no glfw window in Windows instance.
Windows class use AddWindow() to create glfw window, this function should be called externally form Windows class, but the situation is that Editor project don't have the call. So when code run into signal connection, it get an empty pointer and call OnKey() at empty pointer.
To solve it, I hack AddWindow() in Windows class ctor at first. It may disobey the author's design.

After this hack, I continue geting bug of pointer of renderpass is empty. It should be created in RenderStage::Rebuild(), but the function never be called till renderpass is used. After debug, I realize that reanderpass is created in ResetRenderStages(), but my swapchains 's size = 0, so in ResetRenderStages() it doesn't call RenderStage::Rebuild(). Finally I found surface creation is connected to onAddWindow singal, but the connection happen in Graphics class ctor, and I call AddWindow() before the connection, so the onAddWindow invoke nothing.

It means the calling time of AddWindow() should be considered carefully. The calling time should be behind of Windows module creation, behind of modules that connect to onAddWindow, ahead of modules that need glfw window.

So I make the hack in GetWindow()

Sources\Devices\Windows.cpp

Window *Windows::GetWindow(WindowId id) {
	// hack
	if (windows.size() == 0 && id == 0)
		AddWindow();

	if (id >= windows.size())
		return nullptr;
	return windows.at(id).get();
}

Then editor project should run.
