Screenshot of selected CSS element

[rpodcast]

I've been using the webshot package for some side projects and the capability of taking a screenshot of a particular element with CSS selectors (i.e. with webshot("https://www.r-project.org/", "r-sidebar.png", selector = ".sidebar") is really nice. Is it possible to extend this feature to app$takeScreenshot()?

I've done some investigation on ways to integrate this feature, but I'm not sure the optimal approach. In case it helps here's what I've found:

• shinytest currently relies on webdriver to create screenshots via the takeScreenshot() method. Long ago it looks like there was some work to implement a element selection parameter for the screenshot method in webdriver per rstudio/webdriver#13, but the implementation did not perform as expected.
• If there was a way to invokewebshot() on the already running phantomjs session serving the shiny app, then it seems like that could be a solution. Of course I have no idea how difficult it would be to accomplish this.

Duplicate of #260. We should have an implementation of this in the near future.
