Prose is a RichText Rendering which I created because I found the WinRT RichText support woefully inadequate for an application in which RichText is a fundamental element. DirectWrite looked easy(ish) to use so I wrote my own. It's VERY much a work-in-progress and is being driven by my need for it in a separate (closed-source, sorry) personal project. Features will be added as I need them there.
