What is new in SpatialSlideshow 0.9.0

# Spatial Slideshow 0.9.0

Photos can now animate directly from their cached 3D scenes, and you can explore a paused photo with the mouse, trackpad, or WASD. This release also adds a native macOS screen saver and full circular camera motion at higher strengths.

## Changes

- Add **Settings → Playback → Real-time 3D rendering**. It targets 60 fps, skips movie encoding for new scenes, and updates camera movement, duration, framing, and zoom without regenerating the scene. Regular clip playback remains the default; turn realtime rendering off for MP4 export.
- While a live scene is paused, drag over the image, scroll with two fingers, or use **W/A/S/D** to move the camera. Releasing the controls holds the viewpoint; resuming smoothly returns to the slideshow path. Changing photos resets the manual offset. Videos and prepared movie fallbacks pause normally.
- Cache Gaussian scenes across launches with a 4 GiB limit. Active scenes and up to six prepared-ahead scenes are protected; older unused scenes may be regenerated when needed. Existing photo, expansion, and video caches are retained.
- Increase motion strength up to **4×**. Above 2×, paths curve into an orbit; from 2.5× they complete a full circle, with higher strength widening the loop. Existing clips at 2× or below remain reusable.
