EngineMinimal.h no longer includes SlateCore.h or SlateBasics.h
- This nearly halves the time it takes to recompile small game projects! (~14s -> ~8s)
- This shrinks the PCH size for EngineMinimal by 161 MB on Windows (420 MB -> 259 MB, Development Editor Win64)
- Note that Engine.h and EnginePrivate.h still include SlateCore.h and SlateBasics.h (not a clear detriment)
- IMPORTANT: We need to verify all example games that use this still compile, and add release notes for user games that forgot to include Slate directly
- This is all part of UE-7203
