/**
* A replacement for the AquaTabbedPaneUI for Mac OS X 10.2 Jaguar.
* Tabs of tabbed panes are stacked instead of moved into a popup menu,
* if not enough space is available to render all tabs in a single line.
*
* Supports the following client properties on the children of the JTabbedPane:
* Quaqua.TabbedPaneChild.contentBackground specifies the background
* Color to be used to fill the content border.
* Quaqua.TabbedPaneChild.contentInsets specifies the insets
* to be used to lay out the child component inside the JTabbedPane.
