## In https://github.com/rstudio/htmltools/blob/master/R/html_print.R#L41
## html_print doesn't have an option on how and where to write the html
## it always creates anothe temporary directory and writes the HTML there
## This bypasses that with an uglry recursive copy ...

## view from chrome (which can also view PDF inside the browser
