http://source.squeak.org/VMMaker/Cog-eem.430.mcz==================== Summary ====================
Name: Cog-eem.430
Author: eem
Time: 2 January 2021, 1:21:15.936867 pm
UUID: 5fbaa4e2-e023-459c-b431-2899e4145610
Ancestors: Cog-nice.429
Fix a bad estimate of needed heap size in 64=>32 bit image conversions. Provide a convenience for invoking image conversions.
Fix a speeling rorre.
