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

Name: Graphics-mt.516
Author: mt

UUID: 287f8878-a8da-b44d-bd09-07e4c06f3cec
Ancestors: Graphics-mt.515

Fixes MVC drawing issue on platforms with graphics backends that let primitive 126 fail, which was always be possible but only reality on the latest OSVM on macOS using -metal or -core-graphics backends.

Sigh. Come on. Backwards compatibility. I will port this fix back to Squeak 5.3.
