Export pch_table

[atusy]

#2338 did a great job that helps chosing shapes (pch).
Yet, we still have to see vignette to find full name list of shapes.
I'd suggest exporting pch_table, which is currently inside the translate_shape_string.

ggplot2/R/geom-point.r

Line 145 in 2b03e47

pch_table <- c(

Also, I'd suggest pch_table to have a unique class, and implement autoplot method to draw the plot below by autoplot(pch_table)

(from #2075 (comment))

If my suggestion sounds nice, I'd be happy to work on a PR.

Maybe we can just embed this image on the help of scale_shape?

That sounds nice.
BTW, I just noticed the better image is available via an vignette ( https://ggplot2.tidyverse.org/articles/ggplot2-specs.html#point-1).
