Just looked at the mupdf code and it seems it's mupdf's fault. When
mupdf starts it will ask for a certain window size and wait for a
MapNotify event. Every other event (in particular the ConfigureNotify
that tells mupdf about the changed window size) will be discarded.

If we would want to fix mupdf's behavior in dwm we would have to break
other apps that require a resize before being mapped (and a comment in
the dwm code states that there are apps that require this).

Attached is a patch to mupdf's git checkout 657a66bf1c5 which also
applies (with offsets) to 0.9. Maybe there's a better solution but this
works for me.
