WindowGeometry with multi-monitor setup or tiling window manager

[simon04]

I frequently use

• a multi-monitor setup
• the tiling window manager ​i3

When I start JOSM, it may be

• on the left monitor
• on the right monitor
• on one monitor vertically split with another application

Since JOSM remembers the position of many dialogs (using WindowGeometry class), depending on on which monitor I used JOSM the last time,

• the dialog may appear on the right monitor, when JOSM itself is open on the left monitor
• the dialog may appear on the left half of the monitor, when JOSM is open on the right half

This has been bothering me for months (if not years).

For a fix,

• we may allow users to completely disable restoring window geometries
• we may allow users to disable restoring window positions (but recalling window sizes)
• we may calculate window positions relative to the JOSM window (seldom one moves a modal dialog outside the main window)
