clearRect is drawing white instead of clearing to transparent #70

A clear HTML5 canvas should have nothing on it. In my usage, calling ```ctx.clearRect(0, 0, this.canvasWidth, this.canvasHeight)


and then drawing new stuff on the canvas still results in a #FFF rect being put in the resulting SVG. Is there a way to clear the canvas that's to spec with HTML5 canvas?

I too have experienced this problem.

kaldrenon, using ctx._clearCanvas() should work! mind you thats 2 ""s

Yup, this is definitely unexpected behavior.

The Mozilla docs state that clearRect should set the pixels in the area to transparent back.

Why set to white when clearCanvas exists?
