Hi all --

Please report whether I am overlooking something here... It was kind of annoying that my entire TrueType cache was gone after just saving the image and keep on working.

Also see the companion commit TrueType-mt.71.

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

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

Name: Graphics-mt.482
Author: mt
Time: 14 February 2022, 5:39:41.237304 pm
UUID: 4613fffa-7d65-d143-a077-7315d58e8d50
Ancestors: Graphics-mt.481

Changes hibernation behavior of forms to only #hibernate on snapshot-and-quit. Do not #hibernate on snapshop-no-quit.

Why? Makes snapshotting and working with TrueType fonts more smooth/responsive.
