The next revision of 2D graphics will be presented at the upcoming Cologne meeting. As opposed to making everyone wait for the mailing, if you would like, you can access R9, the paper submitted for the pre-meeting mailing, here: https://github.com/cpp-io2d/io2dts/blob/master/papers/P0267R9.pdf .

Even though I'm still reading the paper I feel I should point out something that struct me in the "Introduction", while reading this statement:

"...the design of an input API is inherently reliant on the design of the output API..."

and how it's used as a justification "to only pursue of the input API after the output API design was complete." In my experience I don't see any truth in that statement no matter how hard I try to think about it. Maybe my experience in the user interaction field is limited, but I can't remember a case where a rendering, i.e. output, API was required for the input. Can you provide some reference material to support your claim in this respect?
