* I tried to reuse as much state from BControl as possible, so I removed a few states. * Also made the flags private, and added protected SetInside()/IsInside() methods. * Removed useless BIconButton::ID(). * Adjusted users. * Minor cleanup, automatic white space cleanup. -alpha git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41611 a95241bf-73f2-0310-859d-f6bbb57e9c96
