Code Review

This pull request introduces tooltip support within the _TestWindowingOwner and refactors child window rendering in the multiple windows example. The core changes involve the implementation of _TestTooltipWindowController, the addition of WindowManager.getChildrenOf for cleaner child window management, and new tests for modal dialogs and tooltips. The code is well-structured, but I have a few suggestions to improve documentation and code clarity in line with the repository's style guide.
