RenderRunner cleanup

[hjtran]

While trying to use the RenderRunner, I came across a few warts.

• It accepts a pipeline proto but doesn't use run_portable_pipeline
• Not 100% sure about this but it used dotX instead of dot for one of its subprocess calls
• RenderOptions couldn't be used with .view_as because the init-time validation
• The RenderRunner logging used the root logger instead of the module logger

Thank you, this all looks good. dotX was leftover from testing, really glad you caught this before the release was cut.
