* Made BScrollView work when using it with the layout system.
* Added a layout friendly constructor - it's not so nice to use, though, since the original one already doesn't get a BRect (we just don't need the resizing mode, and have to set the B_SUPPORTS_LAYOUT flag). * Refactored size/frame computation a bit. * Cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28258 a95241bf-73f2-0310-859d-f6bbb57e9c96
