SpineBounds
Data structure representing the computed bounding box of a Spine animation. This class provides both storage for bounds data and utilities to extract bounds from a Spine instance without permanently modifying it.
The bounds include both dimensions (width/height) and anchor point information, which together define the full bounding rectangle of the visible Spine content.
Static Members
Computes the bounding box of a Spine instance and extracts the bounds data. This method temporarily modifies the Spine instance to compute accurate bounds, then restores all original values, ensuring the Spine object remains unchanged.
This is useful when you need to know the exact dimensions of Spine content without affecting its current state or visual appearance.

Instance Members
The horizontal anchor position (0-1 range) within the bounding box. A value of 0 means the anchor is at the left edge, 0.5 is centered, and 1 is at the right edge. This affects how the Spine content is positioned relative to its x coordinate.
The vertical anchor position (0-1 range) within the bounding box. A value of 0 means the anchor is at the top edge, 0.5 is centered, and 1 is at the bottom edge. This affects how the Spine content is positioned relative to its y coordinate.
The width of the bounding box in pixels. This represents the horizontal extent of all visible Spine content.
The height of the bounding box in pixels. This represents the vertical extent of all visible Spine content.
Creates a new SpineBounds instance with default values. All properties are initialized to 0.
