There is no way to have oversized images
Doxygen Awesome provides no way (to my knowledge) to include images wider than textwidth in their original size.
This is most annoying with Dot graphs:
Every Dot graph has a scrollbar beneath it. This is annoying when the graph clearly fits, but it's even worse when it doesn't. It is purely decorative.
I am aware of https://jothepro.github.io/doxygen-awesome-css/md_docs_2tricks.html, but this requires DOT_IMAGE_FORMAT = svg. Graphviz has terrible support for SVGs (anything more than plaintext nodes can lead to broken spacing). The fix is to use svg:cairo, but that is not supported by Doxygen, so only PNGs/JPEGs renders dot graphs properly.
Images have the same problem.
Another issue is that while the image is scaled down, the URLs aren't. If the dot graph contains clickable links, they will likely be misaligned with the image (and quite severely if the original has to be scaled down a lot).
