/*
    Qt Cocoa Accessibility Overview

    Cocoa accessibility is implemented in the following files:

    - qcocoaaccessibility (this file) : QCocoaAccessibility "plugin", conversion and helper functions.
    - qnsviewaccessibility            : Root accessibility implementation for QNSView
    - qcocoaaccessibilityelement      : Cocoa accessibility protocol wrapper for QAccessibleInterface

    The accessibility implementation wraps QAccessibleInterfaces in QCocoaAccessibleElements, which
    implements the cocoa accessibility protocol. The root QAccessibleInterface (the one returned
    by QWindow::accessibleRoot), is anchored to the QNSView in qnsviewaccessibility.mm.

    Cocoa explores the accessibility tree by walking the tree using the parent/child
    relationships or hit testing. When this happens we create QCocoaAccessibleElements on
    demand.
