Anomaly : Transformation Apply followed by Cancel

[pierrelabreche]

Scenario :

• File open
• Apply a Brightness curve ( shape 1 )
• close brightness curve transformation
• reopen brightness curve transformation
• change curve shape ( shape 2 )
• press Apply button
• press Cancel button
• Answer Yes to "Abandon changes"

Outcome : The abandoned change persists (per curve shape 2) ; when reopening the transformation, curve shape 1 is displayed (while shape 2 is still in use).

More fallout from recent optimizations. Same issue in multipass sharpen and add texture transformations. Fixed for next release.
