USD export: fixed typo in comparison.

USD export format fixes.

USD Export: USD Preview Surface conversion.

Added "USD Preview Surface From Nodes" export option,
to convert a Principled BSDF material node tree to an
approximate USD Preview Surface shader representation.

Also added the following options for texture export.

Export Textures: If converting Preview Surface, export
textures referenced by shader nodes to a 'textures'
directory next to the USD file.

Overwrite Textures: Allow overwriting existing texture
files when exporting textures (this option is off by
default).

Relative Texture Paths: Save material texture asset
paths as relative paths in the USD.
