The UsdTransform2d shader was previously ignored, and the material read would stop when it found these nodes. This resulted in many surfaces having their textures mapped incorrectly when imported into Blender, and worse, resulted in the loss of that data when round-tripping back out of Blender. This patch adds support for the Transform 2D node and also ensures that the wrap modes are similarly written correctly.
