please merge in from main, and then look at feature/deepzoom-pivotviewer to make sure we have correctly included all of the deepzoom code, tests, resources and more. |

Integrates PR #366 (Deep Zoom) on top of PR #326 (Gestures) branch, replacing all platform-specific gesture code with SKGestureTracker. ## Core library (SkiaSharp.Extended.DeepZoom) - DZI and DZC format parsing with full compatibility - Tile pyramid math and viewport coordinate transforms - Spring-based animation system (ViewportSpring) - LRU tile cache with deferred disposal - Priority tile scheduler with parent-level fallback - LOD cross-fade blending renderer - HTTP and file-based tile fetchers with cancellation - Deep zoom sub-image support for collections ## MAUI control (SkiaSharp.Extended.UI.Maui.DeepZoom) - SKDeepZoomView now uses SKGestureTracker (from SkiaSharp.Extended) instead of PanGestureRecognizer/PinchGestureRecognizer/TapGestureRecognizer - EnableTouchEvents=true on SKCanvasView, feeds SKTouchEventArgs to tracker - Pan/Pinch/DoubleTap/Scroll/Fling all routed through unified gesture system - Fling momentum scrolling added (deep zoom previously had none) - GestureTracker property exposed for advanced configuration ## Blazor sample (SkiaSharpDemo.Blazor) - DeepZoom.razor migrated from raw mouse events to pointer events - Uses SKGestureTracker with same pointer-event pattern as Gestures.razor - Proper multi-touch support (pinch to zoom on touch screens) - Fling momentum scrolling via tracker FlingUpdated events - DPI scaling via _displayScale computed in PaintSurface ## Tests 489 tests covering all deep zoom APIs (unchanged from PR #366) 413 gesture tests (unchanged from PR #326) - all passing Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
