Implement the USD Plane Shape for import, mirroring what was done for the others. See #134138 Additional tests will be added afterwards but a simple test is simply to import the resulting file: ```python from pxr import Usd, UsdGeom stage = Usd.Stage.CreateNew('plane.usd') xform_prim = UsdGeom.Xform.Define(stage, '/world') plane_prim = UsdGeom.Plane.Define(stage, '/world/plane') stage.GetRootLayer().Save() ``` Co-authored-by: Nig3l <nig3lpro@gmail.com> Pull Request: https://projects.blender.org/blender/blender/pulls/134275
