* further optimized clipping * implemented support for B_FULL_UPDATE_ON_RESIZE flag * added support for hidden layers * implemented Show()/Hide() * implemented Invalidate(region) remains to be done: * fully redraw center and right alligned layers on a resize operation. * additional testing. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12798 a95241bf-73f2-0310-859d-f6bbb57e9c96
