[unity] Fixed outline shaders semi transparent gap around skeleton. All outline shaders now provide a Fill parameter. Closes #2758.

   - SkeletonMecanim: Added `Scene Preview` option to preview an Animation Clip for e.g. easier event placement. When enabled, the Animation Clip selected in the Animation window is previewed in the Scene and Game views. Lock the `SkeletonMecanim` Inspector window, open the Animation window and select the Animation Clip. Then in the Animation window scrub through the timeline to see the current animation frame previewed.
   - `Universal Render Pipeline/Spine/Skeleton Lit` shader now supports [Adaptive Probe Volumes (APV)](https://docs.unity3d.com/6000.0/Documentation/Manual/urp/probevolumes-concept.html) introduced in Unity 6. The shader also provides a new material property `APV per Pixel` to either calculate APV lighting contribution per pixel (the default) or per vertex.
   - `Universal Render Pipeline/Spine/Sprite` shader now also supports [Adaptive Probe Volumes (APV)](https://docs.unity3d.com/6000.0/Documentation/Manual/urp/probevolumes-concept.html) introduced in Unity 6. APV lighting contribution is automatically calculated per pixel.
+  - All Spine Outline shaders, including the URP outline shaders, now provide an additional parameter `Fill`. Enable it to also fill the opaque area inside the outline with the outline color. Prevents a semi-transparent gap between outline and skeleton. Defaults to `disabled` to maintain existing behaviour.
