vncv(1) grabbing was my prime use-case!

There's no need for it to autograb either.
It could grow an option to enable autograb or grab / ungrab
could be done manually with a key -- which is what it does
right now.

During a day of using these patches I found the border hint
to be quite helpful.  In particular after switching my focus
away from the terminal I'd often forget about the state I
left it in; the border hint reminded me that the mouse is
(or isn't) grabbed so I could continue working without
having to probe around to determine the state.

Overall I think this patchset is a very useful addition
to the system. I hope we can agree on the details that make
sense and have it merged soon.

Praise to jmi2k for this work!
