            Bug ID: 215602
           Summary: Newlines in <feColorMatrix values="…"> should be
                    treated as whitespace instead of breaking the filter
           Product: WebKit
           Version: WebKit Nightly Build

                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG

test case showing either a red background (fail) or a green background (pass)

This SVG filter definition doesn't have an effect, because Safari apparently cannot handle the newline characters in the `values` attribute value:

  <filter id="f">
    <feColorMatrix values="
      0 0 0 0 0
      1 1 1 0 0
      0 0 0 0 0
      0 0 0 1 0">
  </filter>

Rewriting the attribute value without any newlines (or dynamically updating the attribute value via JS, as done in the attached test case) causes the filter to work as expected:

  <filter id="f">
    <feColorMatrix values="0 0 0 0 0 1 1 1 0 0 0 0 0 0 0 0 0 0 1 0">
  </filter>

Please support newlines in `<feColorMatrix values>`.
