David T. Lewis uploaded a new version of Graphics to project The Trunk:

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

Name: Graphics-raa.383
Author: raa
Time: 8 October 2017, 8:42:24.504722 am
UUID: 032db0c7-96b0-436f-b882-5ddbeeb9de99
Ancestors: Graphics-topa.382

try to ensure BitBlt>>primDisplayString:from:to:map:xTable:kern: uses the primitive since the fallback code can produce different results (StrikeFont + subPixelRendering turned off + maybe other stuff, e.g.)
