Um... it's been about a year since I sat around looking at the output of any of those three libraries and it wasn't worth the effort to go back and fire something up to be "certain". So I used the appropriate words "I believe" and "I'm pretty sure" to indicate that I was make statements based upon the recollections of my frail human memory ... also, those libraries are actively developed (last I checked) and could have changed since I last used them.
You have no credibility to talk about my credibility if you read too much into every single sentence I write without context.
