Marcel Taeumel uploaded a new version of Graphics to project The Trunk:

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

Name: Graphics-mt.447
Author: mt
Time: 13 April 2021, 2:17:38.592381 pm
UUID: 297ae9ef-ec22-b340-b60d-2639c8765aa4
Ancestors: Graphics-mt.446, Graphics-ct.437, Graphics-ct.419

Merges Graphics-ct.437, Graphics-ct.419 -- which complements Graphics-cbc.372

(Note that I think it makes sense to either let #isIntegerRectangle always decide on rounding or introduce an IntegerRectangle as proposed by Eliot some time ago. Rectangles are usually immutable anyway. http://forum.world.st/The-Inbox-Graphics-cbc-372-mcz-tp4940274p4940451.html)
