Adds 2D world space functionality to Unity's UI Toolkit Document

Utilize this script in your Unity projects to convert screen space UI Toolkit trees/documents into your 2D world space.

The MonoBehaviour script allows:

• Using the attached gameObject's transform to change the tree/documents position, z-axis rotation, and scale in 2D world space.
• Scale in world space based on a reference unit size on either horizontal or vertical axis.
• Additional scaling in world space from the attached transform's localscale.
• Bounding box displayed in editor window using debug lines for easy positioning/reference.

1. Your target UI document has a top tree asset with dimensions (600px, 480px).
2. You set the property unitSize to 16 and the referenceDimension enum to Horizontal.
3. The final world space dimensions of the object would be (16 units, 12.8 units)
4. If the localScale.z of the attached transform was 0.5, the final world space dimensions would be (8 units, 6.4 units).

Do not add a UI Document component to the gameObject, the script attaches this component on initialization and handles instances of the provided PanelSettings.

You can copy the script contents to a local script, or pull the repository and install locally.
