### Bug description

I would like the out-width to equal the fig-width that I have specified in inches in a code chunk. In the documentation it says "[By default figures are displayed using their actual size](https://quarto.org/docs/authoring/figures.html#figure-sizing)" but this does not happen when I have set the dpi of my figure to be larger than the default. I would like the out-width to be equal to the fig-width in terms of the actual space it takes up on my screen rather than the current behaviour where it is much larger if I have set a larger than default dpi. Currently I can only get this outcome by setting all 4 of fig-width, fig-height, out-width and out-height. If the default needs to stay the same could there be a way to set a yaml option that ties out-width to fig-width?

## no options

The figure is created with a size that fits the output space.

```{r}
plot(mtcars[1:4])
```

## fig-height and fig-width specified

If fig-height and fig-width are small relative to the output space the figure will be expanded to fill it. Eg the font size is too large.

```{r}
#| fig-width: 3
#| fig-height: 3
plot(mtcars[1:4])
```

## out-height and out-width specified

Only by setting all 4 can I get a figure that is displayed as the size created it with. Despite this statement in quarto docs "[By default figures are displayed using their actual size](https://quarto.org/docs/authoring/figures.html#figure-sizing)"

```{r}
#| fig-width: 3
#| fig-height: 3
#| out-width: 3in
#| out-height: 3in
plot(mtcars[1:4])
```
