That's just it - by the time XMapRequest is generated the window is
already created.  It just hasn't been mapped.

XMapRequest is closer in spirit to WM_SHOWWINDOW.  WM_CREATE is
equivalent to a (nonexistant) event generated by the XCreateWindow call.

MWF's (actually XplatUIX11.cs's) goal isn't to provide its users with
every X11 event that gets generated.  It's goal is to emulate win32
semantics on top of X11.

I'm not saying a window manager in MWF isn't a interesting project, but
it is also well outside the scope of our goals with MWF, which is to
provide a means for writing cross platform applications, and to allow
migration of applications from windows to linux.

That said, patches will of course be considered.

Qt controls their api - we don't.
