Subject: [PATCH] ns: add macOS Zoom cursor tracking and VoiceOver accessibility Subject: [PATCH] ns: add macOS Zoom cursor tracking and VoiceOver accessibility
Implement dual accessibility support for macOS: Dual accessibility: UAZoomChangeFocus + virtual element tree.
MRC compatible (unsafe_unretained, proper retain/release).
1. UAZoomChangeFocus() in ns_draw_window_cursor: directly tells macOS
Zoom where the cursor is, using CG coordinates.
2. Virtual accessibility tree with EmacsAccessibilityElement base class
and EmacsAccessibilityBuffer (AXTextArea per Emacs window) for
VoiceOver: text content, cursor tracking, window switch notifications.
3. EmacsView provides accessibilityBoundsForRange: for Zoom queries and
legacy parameterized attribute APIs. EmacsView acts as AXGroup
containing EmacsAccessibilityBuffer children.
Uses unsafe_unretained references and proper retain/release (MRC compatible).
