    rsvg-test: Ignore SVG fixtures that start with "ignore-"
    
    Right now pservers-grad-17-b.svg doesn't pass the tests, but I think it
    may be a Cairo bug.
    
    Add the ability to ignore test files if they have a "ignore-" filename
    prefix.  Hopefully I'll remember to fix this later...
