Dynamic Token Ring next steps

[aaclayton]

• Token anchor adjustment should shift the subject within the ring rather than shifting the composited result
• Do we need to expose subject scale correction to the UI?
• Image fit mode should apply to the subject texture but not the ring itself
• How to expose optional ring effects to the UI?
• Fix some fit modes which are not compatible (Fill)

• Expose Token Ring subject scale correction and effects in the Token Config UI. #11139
• Audit all the Token fill modes interaction with Token Rings and implement the changes if necessary #11141
