MultiWindow versus MWExtWM

[Joe Krahn]

What is the history of internal versus external Win32 WMs? It seems that 
Cygwin/X is favoring the internal WM, even though the external WM is a 
better fit to the X server design.

I was looking into adding some NET_WM/EWMH features (mainly icons for 
now), and realized that most things have to be done differently on an 
internal WM, meaning extra work making non-reusable code.

The current external WM is implemented using a proper X extension, which 
might be the source of some problems with the external WM. Maybe an 
efficient solution for the external WM would be to use WndProc hooks, so 
that window message passing can be done natively instead of through an X 
extension.
