Make possible sequential numbering of reference with section numbering activated

[elfunesto]

When using bookdown (single document), if I set both section_numbering = 'yes' and fig_caption = 'yes', the figures are numbered X.2 (where X is the section number). If section_number = 'no', the figures are numbered sequentially (Fig 1, 2 ...), but sections numbers are lost.

Is there a way to get figures numbered sequentially without losing the section numbers? In the example below, I would like to have both the sections figures numbered as 1 and 2.
I had posted this question on stackoverflow and I was suggested to fill an issue.

Thank you.

# header 1
Reference example: \@ref(fig:plotcars):
```{r plotcars, fig.cap = "A car plot"}
plot(cars)
```
# header 2
Reference example: \@ref(fig:plotcars2):
```{r plotcars2, fig.cap = "A car plot"}
plot(cars)
```

I think we can implement this feature by adding an argument whose value is passed to the global argugment of the internal resolve_refs_html function.
Maybe global_refs is the potential name of the argument with !number_sections as a default value in terms of backward compatibility.

bookdown/R/html.R

Line 137 in 8e4551c

x = resolve_refs_html(x, global = !number_sections)

BTW, this feature might be useful in word_document2 when users also want fine controls on fomrats of section numbering via template via reference_docx.
Currently, section-level figure numbering requires word_document2(number_sections = TRUE), which separates section numbers and section contents by a tab.
I prefer a space, but the tab is the choice of pandoc...
global_refs would provide more flexibility for word_dcoument2.

For the record, for HTML documents, pagedown uses this solution to fix a similar issue (rstudio/pagedown#184).

I just added a new argument global_numbering. You can test the development version via

remotes::install_github('rstudio/bookdown')

Example:

---
output: 
  bookdown::html_document2: 
    fig_caption: true
    number_sections: true
    global_numbering: true
---

# header 1

Reference example: \@ref(fig:plotcars):

```{r plotcars, fig.cap = "A car plot"}
plot(cars)
```

# header 2

Reference example: \@ref(fig:plotcars2):

```{r plotcars2, fig.cap = "A car plot"}
plot(cars)
```

Thanks!

I'd like to have my pdf document number figures and tables in the format 1.1, 1.2 etc where the first number is the chapter or section number. The only solution I've found is here: https://stackoverflow.com/questions/53863797/r-markdown-pdf-document2-pdf-figure-and-table-numbers-by-section
Is there a better way?

@daviesmd I don't know if there is a better way. The solution on Stack Overflow doesn't seem to be bad to me.
