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

Name: ToolBuilder-Morphic-ct.264
Author: ct
Time: 17 September 2020, 2:17:24.709813 pm
UUID: f0cb613b-9652-a146-9d77-016577d87700
Ancestors: ToolBuilder-Morphic-mt.263

Initially refresh window color when building a window.

While this also happens later #openInWorld, the call is missing is something else is done with the window instead, e.g. #openInWindow or #imageForm.
