Thanks, any other feedback?  If not I'd like to have these canvas tests approved.

I've checked all the tests in
http://test.w3.org/html/tests/submission/Microsoft/canvas/ and they look valid to me, except canvas_pixelmanipulation_imagedata_001.htm is
incorrect: it calls ctx.getImageData(0, 0, 1, 1) and then assumes imgdata.width == 1. The spec says: "Note: The width and height (w and h) might be different from the sw and sh arguments to the above methods, e.g. if the canvas is backed by a high-resolution bitmap, or if the sw and sh arguments are negative". The test should be changed so that it works regardless of the initial value of imgdata.width.
