This is a false failure, as our default size differs from the one that the test
expects. However, the default size is not a spec requirement, nor is it relevant
to the test. This test is currently being updated upstream.

(WebCore::MeterMac::sizeForBounds const):

`NSLevelIndicatorCell` only knows how to size itself horizontally. Transpose the
size to obtain a vertical size.

(WebCore::MeterMac::draw):

Rotate the graphics context by 90 degrees, relative to the top left of the cell
to render `<meter>` with `appearance: auto` with a vertical writing mode.

This approach is viable since the image does not have any shadows or
orientation specific behaviors.
