cranvas vignette

[Deborah Swayne]

The introduction to the cranvas vignette shows to me some confusion about how this work is currently positioned.

This paper describes a new interactive and dynamic graphics package for R, with essentially the capability of these ancestors. ... The cranvas package is not programmable, but contains a collection of standard plot types supporting interaction and linking between plots. They might be used as examples for others who have ideas and interests in developing different, or new, interactive plots.

That first sentence implies to me that cranvas is a programmable dynamic graphics package, and then two sentences away you say that it isn't.  So what exactly is the programmable package if it isn't cranvas?  Is it actually qtpaint, with the elements of cranvas being examples of what can be programmed?   At the very end of the vignette, I see a list of dependencies, but I'm thinking that you need to clearly separate the toolkit from the cranvas plots, and give it its own special name.

That is, there should be a toolkit which captures everything up to cranvas with its own fancy name, and then cranvas exists as the first package built using the toolkit.    Does that make sense?
