Set DragDropTracker's capture window's size to zero, otherwise, it gets
properties of normal windows such as shadows and also affects the launcher
opacity (since the current size makes it overlap the launcher).

BUG=147407
TEST=manual: starting drag/drop should not trigger wierd visual effects like
shadow animations and also should not affect the opacity of the launcher.
