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

Name: ToolBuilder-Morphic-ct.317
Author: ct
Time: 19 May 2022, 3:47:49.33378 pm
UUID: 5229468a-f32e-ea4a-89f6-fde8487dda34
Ancestors: ToolBuilder-Morphic-mt.316

Proposal: Do not limit the average line length of a pluggable dialog window's message unnecessarily when a larger initial extent was specified.

For later, it would be nice if we had normal window grips instead and the message text would always wrap automatically.

Is there a better pattern for computing the inverse of averageLineLength?
