* introduce B_USE_DEFAULT_SPACING, which works somewhat like B_SIZE_UNSET and B_ALIGN_HORIZONTAL_UNSET * introduce static float BControlLook::ComposeItemSpacing(float spacing), which checks uses be_control_look->DefaultItemSpacing(). * modify layouts to use BControlLook::ComposeItemSpacing() in SetInsets and SetSpacing methods. * default insets are still 0, 0, 0, 0, but can be set to default spacing by passing B_USE_DEFAULT_SPACING * I've found two regressions, patches incoming, please report others on #5614. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38512 a95241bf-73f2-0310-859d-f6bbb57e9c96
