           Summary: Composing a filter with the identity function
                    shouldn't change its effect.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dmazzoni at google.com


Adding an additional identify to the end of a chain of filter primitives, like this, shouldn't change the effect:

   <filter>
     ...other primitives
     <feComponentTransfer>
        <feFuncR type="linear" slope="1" intercept="0"/>
        <feFuncG type="linear" slope="1" intercept="0"/>
        <feFuncB type="linear" slope="1" intercept="0"/>
      </feComponentTransfer>
    </filter>

Repro that demonstrates the problem is attached. Repros in Chromium 25 through 27.
