The editor doesn't use SDL, and OpenGLDrv (even on Windows) is missing 
functionality needed for UnrealEd.

MFC->POSIX is totally meaningless. POSIX doesn't specify any GUI 
widgets, which is more or less the important part of MFC.

A MFC to (say...) wxWindows rewrite might be more reasonable, but is 
also non-trivial.
