Auto-adjust scale and window position when needed.

This is a backport from master to tools_r13

This patch changes the emulator's default behaviour in two ways:

- Automatically compute the window scale to ensure that the emulator's
  window can be displayed within the current screen. This ensures that
  it remains usable when emulating a large-resolution device on a
  small display (e.g. on a 13" laptop running at 1024x768).

  This check and auto-correction do not happen if you use the
  -scale or -dpi-monitor options.

- When re-centering an out-of-focus window, ensure that the top of
  the window is visible (which generally includes the window's
  title bar). This allows the window to be easily moved or minimized
  by the user is needed.

This fixes three bugs:
