[css2-testing] change description about canvas background doesn't match the change

[dbaron]

The changes section of css2-testing (or its equivalent on the CSS2.2 WD on TR) has a change to canvas backgrounds date 2014-07-16.

The change description does not match the change. The change description says that the change makes the canvas background undefined, while the actual change to the spec makes the canvas background transparent. I suspect transparent is correct, although I'm not sure.

Yes, transparent is correct. The WG decided first (2014-07-09) that the canvas background was not taken from the root element, without saying what it was taken from instead. I proposed corresponding errata text that said the background was "undefined". The WG reviewed the text and decided[1] (2014-07-16) to replace "undefined" by "transparent". I updated the errata accordingly, but indeed forgot to update the explanation. I've updated that now, too. Thanks for the review!
