Inherent frame delay? about imgui

[Wyverex42]

There is another issue with the standalone application change. There is never a time now where you're not in an ImGui frame since EndFrame and BeginFrame are called back to back. That means it's not possible to e.g. add a new font because that's not allowed while in a frame.

To add a new font I'd now have to change FImGuiContext::Initialize and add it before the first BeginFrame is called.

This is due to a recent change to support standalone applications which don't go through the regular engine frame loop. I'll have to think about how to accommodate both flows but you can refer to the previous implementation that utilised FCoreDelegates::OnBeginFrame and FCoreDelegates::OnEndFrame that should fix this - see the changes to FImGuiContext in 054095b.

Ah thanks, that makes sense. It's not super time critical, I can live with this issue for a while. So if you're going to fix it properly for both cases in the near future, I can happily wait for that :)
