==================== Summary ====================

Name: System-mt.1253
Author: mt
Time: 25 November 2021, 2:32:49.237354 pm
UUID: 6ef62b9e-a8df-614a-b378-4c876e2d16a8
Ancestors: System-ct.1252

Complements Morphic-mt.1802.

Here is the original comment, I forgot to append to 1802:

This changeset complements the refactoring from System-mt.1240 intended to decouple the base system from Shout. In various places, there were still hard-coded references to SHTextStylerST80 that did not use the new TextStyler abstraction. These accesses are redirected correctly with this changeset. Furthermore, the TextStyler interface is updated to not automatically set a styler if it has been set to nil manually. This makes it possible to opt-out to styling via ShoutCore-ct.88.
