Strawman removal of Image Profile

Good morning/evening,

Please find at [1] an initial stab at exploring the removal of the
Image Profile from the next edition, as suggested at [2]. I have so
far not seen concrete concerns about this removal. [ed.: my only
significant concern, in light of this strawman, is slipping the
schedule.]

[2] https://github.com/w3c/imsc/issues/600

Couple of notes:

- "TTML Profiles for Internet Media Subtitles and Captions 1.2"
becomes "IMSC Text Profile 1.3"
- alternative text features were permitted in Text Profile 1.2, but
were really only useful for the Image Profile. The strawman prohibits
them in Text Profile 1.3 (because they are no longer useful), but that
makes Text Profile 1.3 not a strict superset of  Text Profile 1.2.

Looking forward to your feedback. Do not hesitate to submit your
thoughts on the pull request [1].

I recommend we come to a decision by month's end so that the project
can be completed by year's end.

Best,

-- Pierre
