The current behaviour of XDRIVER is this:

1. The initial state of WM_NORMAL_HINTS has flags USSize|USPosition.

2. When a client connects, unless a redraw is in progress, the flags
are set to PSize|PMinSize|PMaxSize, with all three sizes equal to the
window's current size (as returned by XGetWindowAttributes()).

3. When a client disconnects, the flags are set to PSize.

Note that state 1 is transient; the initial mon.select will change the
state to 3.

XDRIVER doesn't specify a _MWM_HINTS property, but then neither do any
of the other applications which I checked.

BTW, I'm open to comments as to whether the existing behaviour is
correct. It's arguable that it shouldn't be using the US* flags unless
the XDRIVER_* environments variables are set. Also, whether to specify
the position when XDRIVER_{LEFT,TOP} are unset is a matter of
preference. Personally I'd rather let the WM place it, but this won't
happen if the program always requests a specific location.
