Android: Repaint affected areas when window moves

Browse Source 
There are no automatic updates of the window when it moves, since
this is not required on most platforms. This broke drag and drop on
Android, because drag and drop creates a temporary window containing
a pixmap with a snapshot of its content. We need to make sure the old
and new location of the window is repainted when it has moved.

[ChangeLog][Android] Fixed repaint issues in drag and drop.
