[mst-content-hint] highly detailed text in video content (#35)

aphillips has just created a new issue for https://github.com/w3c/mst-content-hint:

== highly detailed text in video content ==
MediaStreamTrack Content Hints, ยง2.2 Video Content Hints
https://www.w3.org/TR/2018/WD-mst-content-hint-20180703/#video-content-hints

> The track should be treated as if video details are extra important, and that significant sharp edges and areas of consistent color can occur frequently. This is generally applicable to presentations or web pages with text content. This setting would normally optimize for detail in the resulting individual frames rather than smooth playback, and may take advantage of encoder tools that optimize for text rendering. Artefacts from quantization or downscaling that make small text or line art unintelligible should be avoided. 

Different written scripts might require different levels of detail (e.g., so that small features such as aspiration marks can be distinguished), and even a video content hint with a value of "text" might not be adequate for some scripts. Perhaps a "health warning" that a value of "text" provides no guarantee that textual features can be distinguished might be helpful.
