Description of issue:
NeoForge fires the ScreenEvent.BackgroundRendered event at the end of Screen.renderBackground
Unfortunately, most (all?) vanilla GUIs override the renderBackground method and do not call super.renderBackground, so the event is not fired from most GUIs.

There seems to be a similar problem with ContainerScreenEvent.Render.Background, which is only fired from AbstractContainerScreen.render and not always fired from child classes like AbstractFurnaceScreen, CraftingScreen, etc.

It seems like the events need to be fired from many new places in order to be consistent.
I do not have a great solution for this problem, so I opened an issue instead of a PR.

net.neoforged.neoforge.common.NeoForge.EVENT_BUS.post(new net.neoforged.neoforge.client.event.ScreenEvent.BackgroundRendered(this,  graphics));

likely needs to be called in the renderBackground after the renderBg call in AbstractContainerScreen. given AbstractContainerScreen doesn't call super since it shouldn't be doing the blurring that happens on something like the esc menu

That being said, I don't know what all is really expected to be called in the event.
