Fixes from Opus maintainer review:
1. [BLOCKER] Zoom code completely removed from ALL intermediate patches
(0005-0007 no longer have UAZoom/overlayZoom at any commit point)
2. [BLOCKER] Unified cursor rect ivar: lastCursorRect (was split
between lastZoomCursorRect and lastAccessibilityCursorRect)
3. [HIGH] Child frame static vars moved to EmacsView ivars
(childFrameLastCandidate/Buffer/Modiff — no cross-frame interference)
4. [HIGH] intern_c_string replaced with Qbefore_string/Qafter_string
5. [MEDIUM] Zoom fallback gated by zoomCursorUpdated flag (no double call)
Major changes:
1. Zoom separated into standalone patch 0000
- UAZoomChangeFocus in ns_draw_window_cursor
- Fallback in ns_update_end for window-switch tracking
- No overlayZoomActive (source of split/switch/move bug)
2. VoiceOver patches 0001-0008 are now Zoom-free
- All UAZoom*, overlayZoom*, kUAZoomFocus references removed
- lastAccessibilityCursorRect kept for VoiceOver bounds queries
- Commit messages cleaned of Zoom references
3. README.txt and TESTING.txt rewritten for new structure
Addresses reviewer (Stéphane Marks) feedback:
- Keep Zoom patch separate from VoiceOver work
- Design discussion needed for non-Zoom patches
- Performance: ns-accessibility-enabled=nil for zero overhead
