test case

Open the attached test case. The circle with the feColorMatrix is not rendered. The "values" attribute of the feColorMatrix is written like that:

            values=" 0 0 0 0 0
                    1 1 1 1 0
                    0 0 0 0 0
                    0 0 0 1 0" />

The leading whitespaces breaks the filter parsing and causes nothing to be rendered.

Look at the SVGNumberListValues::parse() and you will find this comment:

// The spec (section 4.1) strangely doesn't allow leading whitespace. We might choose to violate that intentionally.

This test case works as expected in Chrome and FireFox.
