Image improvements (#391)
Not all PNGs are gone, as several don't seem to have corresponding drawio files. We might have to recreate these later. Some SVGs have embedded PNG data in them, as well. Some other changes were made, like replacing a table images with actual markdown tables, and the trademarks image with a normal HTML element. --------- Co-authored-by: Rafal Bielski <[email protected]>
