Poor exported plot resolution

Describe the bug

I'm using a macbook, so a high resolution screen. I enabled the httpgd plot panel, it looks great, as if rendering svg plots, but once I export a plot the resolution is very low dpi. I don't see any way to change that other than exporting to svg, which is not my goal.

To Reproduce

1. Open the R terminal
2. Create a simple plot like plot(c(1,2,3))
3. Export it from the plot viewer

Can you fix this issue by yourself? (We appreciate the help)

No

(If yes,) can we assist you with anything?

A new setting to set export resolution or some workaround that I'm missing.

(If applicable) Please attach setting.json

Environment (please complete the following information):

• OS: macOS
• VSCode Version: 1.106.3
• R Version: 4.5.2
• vscode-R version: 2.8.6

No file or test is named in the issue; start by reproducing the export from the VS Code plot viewer with the provided R example and compare it with the viewer's high-resolution display. Done means exported raster plots are clear at an appropriate resolution, either through a usable resolution setting or an equivalent fix.
