* Made sure the tool tip stays on screen without moving itself below the cursor;
I'm afraid there is nothing left of stippi's earlier solution. This fixes bug #5097. * The alignment as specified in the BToolTip is now respected. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34616 a95241bf-73f2-0310-859d-f6bbb57e9c96
