WindowManager: scale windows to their monitor's corner on minimize

We previously scaled windows to (primary.x, 0), which is wrong if the
primary monitor is not at y == 0. At the same time, change the policy
to pick the hot corner on the monitor the window is on, because that's
closest to where it will appear in the overview.
