[css-compositing] 'destination' compositing mode in Canvas?

Hi,

Stephen from Blink noted that the compositing mode ‘destination’[1] was not implemented in Blink. I checked other browsers and in fact it doesn’t seem to be implemented anywhere.

Since ‘destination’ doesn’t seem to be very useful, I wonder if browsers should spend the efforts to implement this compositing mode, or if we should drop it from the supported compositing modes on Canvas’s globalCompositeOperation attribute.

Implementing it just because it is one of the Porter-Duff modes doesn’t seem to legitimate the efforts IMO. What do others think? Were there request to support this compositing mode?

Greetings,
Dirk
