This 3 tests pass on the GTK port.

Expected to fail, but passed: (3)
  imported/w3c/css/css-color-3/t422-rgba-onscreen-b.xht
  imported/w3c/css/css-color-3/t422-rgba-onscreen-multiple-boxes-c.xht
  imported/w3c/css/css-color-3/t425-hsla-onscreen-multiple-boxes-c.xht


I'm going to unskip them on the GTK TestExpectations

Chrome also fails these. I think the tests may make assumptions about how the OS does color compositing.
