Re: [css-compositing] SVG transforms and isolation

All,

currently transforms are listed as a property that causes isolation [1].
After talking this over with developers on blink and WebKit, I would like to drop that requirement and have them NOT cause isolation. Instead, an element with a transform should still allow access to its backdrop.

With the current code in WK and blink, we would have to go out of our way to implement the currently specified behavior. Not only will it slow down rendering, it will also increase memory since we'd have to create an extra intermediate buffer.

Heh, that's good news. Transforms causing isolation in SVG would have sucked.

In addition, since SVG uses transforms all the time, blending would become almost impossible to use.

Can I make that change to the spec?

I support this change.
