Marcel Taeumel uploaded a new version of MorphicExtras to project The Trunk:
http://source.squeak.org/trunk/MorphicExtras-ct.260.mcz
==================== Summary ====================
Name: MorphicExtras-ct.260
Author: ct
Time: 4 September 2019, 3:53:54.175698 pm
UUID: cab65f78-e646-cc40-9d0f-c16114d1bb44
Ancestors: MorphicExtras-mt.259
Refactor FrameRateMorph: Add accessors for updateInterval and expose measure data. Use TimeStamp instead of Time to avoid clock wrap around.
