Addresses:
=> Fix folder icon drop location mapping (was very far off)
=> Fix BubbleTextView drop animation shifted by a few pixels
=> Get rid multiple unnecessary calls to setDragMode(none), was breaking
some of the reorder flow; still some issues to address here.
=> Fix folder icon parallax (didn't work when the folder had a dot)
Test: manual
