Maya Looks: support for renderman PxrTexture

[antirotor]

Feature

We need to add support for Renderman's texture node PxrTexture in look collector.

Actually - can you test whether this works for PxrTexture?

I would recommend refactoring the Look Collector to that. It will basically support any plug-in's File nodes or nodes that contain input files which the Plug-in maintainers have registered with Maya's system.

It would likely allow us to avoid this whole "if type == x" shebang in the Collect Look and be more Maya generic in general.

I think we must refactor collect/extract look in more depth - add more generic renderer support, better support for various "maketx" tools and so on. For now, I used "old" style just to quickly add support for renderman for the client. We'll still need to handle various attribute names for file path on texture node, fact that sometime (in case of renderman) there isn't for example colorspace attribute and it's equivallent and so on. And I agree it would be nice to get rid of those pesky conditions.
