CPScrollView previously lacked magnification support, preventing document
zooming and leaving view scaling infrastructure without practical test coverage.
Additionally, views resetting to a 1.0 scale retained stale CSS transform properties,
and legacy cibs compiled via nib2cib omitted explicit magnification limits,
breaking zoom functionality in older archives.
* AppKit/CPScrollView.j:
- Implement magnification methods and properties (`magnification`, `setMagnification:`, `setMagnification:centeredAtPoint:`, `allowsMagnification`, `minMagnification`, and `maxMagnification`) modelled on NSScrollView, with keyed archiving.
- Scale clip view bounds and synchronize resizing document view widths.
- Define standard Cocoa default limits (0.25 and 4.0) as named constants.
- Implement robust decoding validation to assign default limits to unset or invalid archive values and reject non-positive magnification inputs, ensuring full compatibility with legacy cibs.
* AppKit/CPView.j:
- Remove stale CSS scale styling when a view's scale factor returns to 1.0.
* Tests/AppKit/CPScrollViewTest.j:
- Add comprehensive unit tests covering magnification scaling, archiving, and fallback decoding for unconfigured limits.
* Tests/Manual/TextEditor/DocumentWindowController.j:
- Implement zoom action handlers (`zoomToLevel:`, `zoomToActualSize:`, `zoomIn:`, and `zoomOut:`) driven by menu item tag values.
* Tests/Manual/TextEditor/Resources/MainMenu.xib, MainMenu.cib:
- Add View menu options for Actual Size, Zoom In, Zoom Out, and explicit Zoom Levels (25% to 200%).
* Tests/Manual/TextEditor/WORKLIST.md:
- Mark zoom functionality as tested; log discovered scaling edge cases as open items.
CPScrollView and TextEditor now support robust document magnification from 25% to 200%, validating core view scaling mechanics.
