sam and tiling

[Castor Fu]

Do people like the window creation mechanism on sam?  I found that more often
then not,  I didn't really want to choose a particular window size, but
simply wanted to put one somewhere.  

However, the current behavior with the single click didn't seem to quite 
agree with me.

Taking a cue from Oberon and acme, I decided to patch getr in samterm/main.c
by adding the following in the appropriate place:
modifying the code like so:

			if (p.y <= r.min.y)
				rp->max.y = r.min.y;
			else if (p.y >= r.max.y)
				rp->min.y = r.max.y;
			else {
				rp->min.y = r.min.y;
				rp->max.y = r.max.y;
			}
[and similarly  for the x coords].
This allows the command window to define 8 other sectors, which don't 
overlap.  I've been working with it for a few hours now, and I feel the screen
real estate is better utilized.
