image with src set to data:image/png should be considered as same origin, as we fixed in Bug 1373513. So this reverts what we did in bug 1363673.

For image types that do not support an alpha channel, the image must be
|
|
composited onto a solid black background using the source-over operator,
|
|
and the resulting image must be the one used to create the data: URL.

Author's note:
|
|
To add more cases to this test:
|
|
- To add a row (another color value)
|
|
* Add a row to the table below, using the canvas id format
|
|
(c<row>-<col>)
|
|
* Update runTests to include the new row in the loop
|
|
- To add a column (another image format)
|
|
* Add a column to the table below, using the canvas id format above
|
|
* Update runTests to call do_canvas, passing your column number,
|
|
the image format, and any options to pass to the toDataUrl function
