Tackle limitation of point coordinate system

[akoch-yatta]

There are some scenarios, e.g. with detached views in the IDE, where point to pixels conversion lead to unexpected results:

Scenario 1 (e.g. detached preview)

Fetch a point are rectangle on one monitor and change it programmatically to another monitor (with a different zoom) before using it again:

Point l = shell.getLocation();
l.x += 30;
shell.setLocation(l);

Scenario 2 (e.g. Eclipse view D&D)

E.g.
Control::getBounds().contains(getCursor)

Scenario 3 (Maximized window)

getBounds with maximized windows -> getBoundsInPixel gives position with x/y shifted by 8 outside of monitor

As discussed in the daily, we will rediscuss this issue and possible solutions
