regression: SimpleCocoaVTK example now logs "Failed to get red color buffer size"
Since !9725 (merged) commit !9725 (5490f7cc) there's now a warning/error in the SimpleCocoaVTK example: "Failed to get red color buffer size"
I'm not certain if the behaviour causes actual problems, but the log itself is bothersome.
It was changed from an error to a warning in !9929 (4b1a5d8f) which is less disruptive.
It only happens with the rightmost (of 3) views in SimpleCocoaVTK. This view is different in that it uses a CALayer for drawing. (My VTK-based application does the same.)
