Bug sf-3034038: panning while window is unfocused

[apoelstra]

Add event handler for window losing focus that disables auto-pan.
Otherwise when you alt+tab while using some tools, PCB will pan in the background, which is very irritating.

The patch is now obsolete, as the auto-pan feature was removed..

    hid/gtk: Remove auto-pan feature (kill it with fire).

    This seems to be fairly universally unpopular on geda-user, and its
    implementation is a little fragile, often leading the board to pan off
    to some corner of the board as the poor user reaches for the layer
    selector or a menu without having remembered to click the feature off.

    The fact that the pan direction and speed was set the instant you leave
    the drawing window also made it particularly unhelpful. A proper
    implementation should have grabbed the mouse - or at least implemented
    some buffer zone in which the mouse could be used to give feedback on
    the pan direction.

This is good news! :-)
I'll update the gschem tips in the wiki and mark Bug#804461 as fix commited, too.

The above should "PCB tips", rather than "gschem tips".
(Can't find a way to correct my comment)
