[9fans] libcontrol focus question

["Anthony Sorace" <anothy@gmail.com>]

In my first experiment with control(2),  I'm trying to get fgui to
give the first entry box focus when the window is created (since in
better than 90% of my cases, all that's needed is a password). I've
tried a few methods, all of which basically boil down to:
	chanprint(cs->ctl, "%s focus 1", entry[i].val);
It seems like it should be possible to explicity tell a control that
it has focus, separate from the clicktotype flag, which I understand
to determine how the controlset normally decides to send those
messages. That's my reading of control(2)'s discussion of messages,
anyway.

It's entirely possible I'm missing something with the interaction
between direct updates to the Controls, activate, and
resizecontrolset, which is what I'm going to look at in the morning,
but it seems prudent to ask if this is even possible.

Can one explicitly determine which Control in a set has focus?
