I'd like to achieve the following intelligent scaling of inline images:
image-actual-width > 800: scale it down to 800
Else: display image without any further scaling
(setq org-image-actual-width 800) achieves the first part, but for smaller images it scales them up to 800, which I want to avoid.
I'd like to have this as a sane default - I know I can set buffer and image specific widths via attributes.
