Review heuristics used for embedding screenshots in a landscape document

Specifically org-odt-max-image-size is meant for portrait documents, and it gives less than perfect sizes for "big" images.

Based on whether the image is landscape or portrait and if the page is landscape or portrait, I believe there is a way for go with rel-height or rel-width for the image.
