This patch replaces the bespoke rendering engine in Presenter with a simple pipeline that turns presentations into single-page HTML files. The HTML is then loaded into an OutOfProcessWebView. This achieves a number of things, most importantly: - Access to all the CSS features supported by LibWeb - Sandboxed, multi-process rendering The code could be simplified a lot further, but I wanted to get the new architecture in place without changing anything about the file format.
