Subject: Re: Canvas API maintenance (Blend Modes)

In addition to ImageOps... We had decided later on that we would drop the strange behavior of the CompositeOperations in Canvas and simply support the JavaFX BlendModes.

We decided BlendMode was a better name than composite because it is consistent with other JavaFX API.

Trivial Change to the API can be seen below:

import javafx.scene.effect.BlendMode;

...

   /**
     * Sets the Global Blend Mode of the current state.
     * 
     * @param op
     */
    public void setGlobalBlendMode(BlendMode op);
    
    /**
     * Gets the Global Blend Mode of the current state.
     * 
     * @return CompositeOperation 
     */
    public BlendMode getGlobalBlendMode();
